Add error handling for unsupported files

This PR introduces:
1. a new /files/ POST endpoint in the local runner that supports
   uploading a file to a folder that must be provided at runtime
2. By default, the runner will allow a maximum 10 files to be
   saved
3. Added logic to the send-file handler in RTVI to read a file
   from disk if the file provide is a url starting with '/files/'

-## [0.0.107] - 2026-03-23
-
-### Added
-
-- Added `frame_order` parameter to `SyncParallelPipeline`. Set
-  `frame_order=FrameOrder.PIPELINE` to push synchronized output frames in
-  pipeline definition order (all frames from the first pipeline, then the
-  second, etc.) instead of the default arrival order.
-  (PR [#4029](https://github.com/pipecat-ai/pipecat/pull/4029))
-
-- Added `sync_with_audio` field to `OutputImageRawFrame`. When set to `True`,
-  the output transport queues image frames with audio so they are displayed
-  only after all preceding audio has been sent, enabling synchronized
-  audio/image playback.
-  (PR [#4029](https://github.com/pipecat-ai/pipecat/pull/4029))
-
-- Added `OpenAIResponsesLLMService`, a new LLM service that uses the OpenAI
-  Responses API. Supports streaming text, function calling, usage metrics, and
-  out-of-band inference. Works with the universal `LLMContext` and
-  `LLMContextAggregatorPair`. See
-  `examples/foundational/07-interruptible-openai-responses.py` and
-  `14-function-calling-openai-responses.py`.
-  (PR [#4074](https://github.com/pipecat-ai/pipecat/pull/4074))
-
-- Added `audio_out_auto_silence` parameter to `TransportParams` (defaults to
-  `True`). When set to `False`, the transport waits for audio data instead of
-  inserting silence when the output queue is empty, which is useful for
-  scenarios that require uninterrupted audio playback without artificial gaps.
-  (PR [#4104](https://github.com/pipecat-ai/pipecat/pull/4104))
-
-### Changed
-
-- Renamed tracing span attributes to align with OpenTelemetry GenAI semantic
-  conventions: `gen_ai.system` to `gen_ai.provider.name`, `system` to
-  `gen_ai.system_instructions`, `gen_ai.usage.cache_read_input_tokens` to
-  `gen_ai.usage.cache_read.input_tokens`, and
-  `gen_ai.usage.cache_creation_input_tokens` to
-  `gen_ai.usage.cache_creation.input_tokens`.
-  (PR [#3449](https://github.com/pipecat-ai/pipecat/pull/3449))
-
-- `DeepgramSageMakerTTSService` now correctly routes audio through the base
-  `TTSService` audio context queue. Audio frames are delivered via
-  `append_to_audio_context()` instead of being pushed directly, enabling proper
-  ordering, interruption handling, and start/stop frame lifecycle management.
-  Interruptions now trigger a `Clear` message to Deepgram (flushing its text
-  buffer) at the right time via `on_audio_context_interrupted`.
-  (PR [#4083](https://github.com/pipecat-ai/pipecat/pull/4083))
-
-- `GradiumTTSService` now sends a per-context `setup` message with
-  `client_req_id` before the first text message for each TTS context, following
-  Gradium's multiplexing protocol. Previously, a single setup message was sent
-  at connection time without a `client_req_id`, which prevented Gradium from
-  associating requests with their sessions when using `close_ws_on_eos=False`.
-  (PR [#4091](https://github.com/pipecat-ai/pipecat/pull/4091))
-
-### Fixed
-
-- Fixed stale `system_instruction` in LLM tracing spans by reading from
-  `_settings.system_instruction` instead of the removed `_system_instruction`
-  attribute.
-  (PR [#3449](https://github.com/pipecat-ai/pipecat/pull/3449))
-
-- Fixed `SyncParallelPipeline` breaking the Whisker debugger.
-  (PR [#4029](https://github.com/pipecat-ai/pipecat/pull/4029))
-
-- Fixed `SyncParallelPipeline` race condition where concurrent SystemFrame
-  processing (e.g. from RTVI) could corrupt sink queues and cause deadlocks.
-  SystemFrames now take a fast path that passes them through without draining
-  queued output.
-  (PR [#4029](https://github.com/pipecat-ai/pipecat/pull/4029))
-
-- Fixed TTS frame ordering so that non-system frames always arrive in correct
-  order relative to the `TTSStartedFrame`/`TTSAudioRawFrame`/`TTSStoppedFrame`
-  sequence. Previously these frames could race ahead of or behind audio context
-  frames, producing out-of-order output downstream.
-  (PR [#4075](https://github.com/pipecat-ai/pipecat/pull/4075))
-
-- Fixed `SarvamTTSService` audio and error frames now route through
-  `append_to_audio_context()` instead of `push_frame()`, ensuring correct
-  behavior with audio contexts and interruptions.
-  (PR [#4082](https://github.com/pipecat-ai/pipecat/pull/4082))
-
-- Fixed audio frame ordering and interruption handling in Fish Audio, LMNT,
-  Neuphonic, and Rime NonJson TTS services. These services were bypassing the
-  base `TTSService` audio context serialization queue by pushing audio frames
-  directly, which could cause out-of-order frames and broken interruptions
-  during speech.
-  (PR [#4090](https://github.com/pipecat-ai/pipecat/pull/4090))
-
-- Fixed Genesys AudioHook serializer to always include the `parameters` field in
-  protocol messages. The AudioHook protocol requires every message to carry a
-  `parameters` object (even if empty), but `_create_message` omitted it when no
-  parameters were provided. This caused clients that validate message structure
-  (including the Genesys reference implementation) to reject `pong` and
-  parameter-less `closed` responses, breaking server sequence tracking and
-  preventing `outputVariables` from reaching the Architect flow.
-  (PR [#4093](https://github.com/pipecat-ai/pipecat/pull/4093))
-
-## [0.0.106] - 2026-03-18
-
-### Added
-
-- Added optional `service` field to `ServiceUpdateSettingsFrame` (and its
-  subclasses `LLMUpdateSettingsFrame`, `TTSUpdateSettingsFrame`,
-  `STTUpdateSettingsFrame`) to target a specific service instance. When
-  `service` is set, only the matching service applies the settings; others
-  forward the frame unchanged. This enables updating a single service when
-  multiple services of the same type exist in the pipeline.
-  (PR [#4004](https://github.com/pipecat-ai/pipecat/pull/4004))
-
-- Added `sip_provider` and `room_geo` parameters to `configure()` in the Daily
-  runner. These convenience parameters let callers specify a SIP provider name
-  and geographic region directly without manually constructing
-  `DailyRoomProperties` and `DailyRoomSipParams`.
-  (PR [#4005](https://github.com/pipecat-ai/pipecat/pull/4005))
-
-- Added `PerplexityLLMAdapter` that automatically transforms conversation
-  messages to satisfy Perplexity's stricter API constraints (strict role
-  alternation, no non-initial system messages, last message must be user/tool).
-  Previously, certain conversation histories could cause Perplexity API errors
-  that didn't occur with OpenAI (`PerplexityLLMService` subclasses
-  `OpenAILLMService` since Perplexity uses an OpenAI-compatible API).
-  (PR [#4009](https://github.com/pipecat-ai/pipecat/pull/4009))
-
-- Added DTMF input event support to the Daily transport. Incoming DTMF tones
-  are now received via Daily's `on_dtmf_event` callback and pushed into the
-  pipeline as `InputDTMFFrame`, enabling bots to react to keypad presses from
-  phone callers.
-  (PR [#4047](https://github.com/pipecat-ai/pipecat/pull/4047))
-
-- Added `WakePhraseUserTurnStartStrategy` for triggering user turns based on
-  wake phrases, with support for `single_activation` mode. Deprecates
-  `WakeCheckFilter`.
-  (PR [#4064](https://github.com/pipecat-ai/pipecat/pull/4064))
-
-- Added `default_user_turn_start_strategies()` and
-  `default_user_turn_stop_strategies()` helper functions for composing custom
-  strategy lists.
-  (PR [#4064](https://github.com/pipecat-ai/pipecat/pull/4064))
-
-### Changed
-
-- Changed tool result JSON serialization to use `ensure_ascii=False`,
-  preserving UTF-8 characters instead of escaping them. This reduces context
-  size and token usage for non-English languages.
-  (PR [#3457](https://github.com/pipecat-ai/pipecat/pull/3457))
-
-- `OpenAIRealtimeSTTService`'s `noise_reduction` parameter is now part of
-  `OpenAIRealtimeSTTSettings`, making it runtime-updatable via
-  `STTUpdateSettingsFrame`. The direct `noise_reduction` init argument is
-  deprecated as of 0.0.106.
-  (PR [#3991](https://github.com/pipecat-ai/pipecat/pull/3991))
-
-- Updated `sarvamai` dependency from `0.1.26a2` (alpha) to `0.1.26` (stable
-  release).
-  (PR [#3997](https://github.com/pipecat-ai/pipecat/pull/3997))
-
-- `SimliVideoService` now extends `AIService` instead of `FrameProcessor`,
-  aligning it with the HeyGen and Tavus video services. It supports
-  `SimliVideoService.Settings(...)` for configuration and uses
-  `start()`/`stop()`/`cancel()` lifecycle methods. Existing constructor usage
-  (`api_key`, `face_id`, etc.) remains unchanged.
-  (PR [#4001](https://github.com/pipecat-ai/pipecat/pull/4001))
-
-- Update `pipecat-ai-small-webrtc-prebuilt` to `2.4.0`.
-  (PR [#4023](https://github.com/pipecat-ai/pipecat/pull/4023))
-
-- Nova Sonic assistant text transcripts are now delivered in real-time using
-  speculative text events instead of delayed final text events. Previously,
-  assistant text only arrived after all audio had finished playing, causing
-  laggy transcripts in client UIs. Speculative text arrives before each audio
-  chunk, providing text synchronized with what the bot is saying. This also
-  simplifies the internal text handling by removing the interruption re-push
-  hack and assistant text buffer.
-  (PR [#4042](https://github.com/pipecat-ai/pipecat/pull/4042))
-
-- Updated `daily-python` dependency to 0.25.0.
-  (PR [#4047](https://github.com/pipecat-ai/pipecat/pull/4047))
-
-- Added `enable_dialout` parameter to `configure()` in `pipecat.runner.daily`
-  to support dial-out rooms. Also narrowed misleading `Optional` type hints and
-  deduplicated token expiry calculation.
-  (PR [#4048](https://github.com/pipecat-ai/pipecat/pull/4048))
-
-- Extended `ProcessFrameResult` to stop strategies, allowing a stop strategy to
-  short-circuit evaluation of subsequent strategies by returning `STOP`.
-  (PR [#4064](https://github.com/pipecat-ai/pipecat/pull/4064))
-
-- `GradiumSTTService` now takes both an `encoding` and `sample_rate`
-  constructor argument which is assmebled in the class to form the
-  `input_format`. PCM accepts `8000`, `16000`, and `24000` Hz sample rates.
-  (PR [#4066](https://github.com/pipecat-ai/pipecat/pull/4066))
-
-- Improved `GradiumSTTService` transcription accuracy by reworking how text
-  fragments are accumulated and finalized. Previously, trailing words could be
-  dropped when the server's `flushed` response arrived before all text tokens
-  were delivered. The service now uses a short aggregation delay after flush to
-  capture trailing tokens, producing complete utterances.
-  (PR [#4066](https://github.com/pipecat-ai/pipecat/pull/4066))
-
-### Deprecated
-
-- `SimliVideoService.InputParams` is deprecated. Use the direct constructor
-  parameters `max_session_length`, `max_idle_time`, and `enable_logging`
-  instead.
-  (PR [#4001](https://github.com/pipecat-ai/pipecat/pull/4001))
-
-- Deprecated `LocalSmartTurnAnalyzerV2` and `LocalCoreMLSmartTurnAnalyzer`. Use
-  `LocalSmartTurnAnalyzerV3` instead. Instantiating these analyzers will now
-  emit a `DeprecationWarning`.
-  (PR [#4012](https://github.com/pipecat-ai/pipecat/pull/4012))
-
-- Deprecated `WakeCheckFilter` in favor of `WakePhraseUserTurnStartStrategy`.
-  (PR [#4064](https://github.com/pipecat-ai/pipecat/pull/4064))
-
-### Fixed
-
-- Fixed an issue where the default model for `OpenAILLMService` and
-  `AzureLLMService` was mistakenly reverted to `gpt-4o`. The defaults are now
-  restored to `gpt-4.1`.
-  (PR [#4000](https://github.com/pipecat-ai/pipecat/pull/4000))
-
-- Fixed a race condition where `EndTaskFrame` could cause the pipeline to shut
-  down before in-flight frames (e.g. LLM function call responses) finished
-  processing. `EndTaskFrame` and `StopTaskFrame` now flow through the pipeline
-  as `ControlFrame`s, ensuring all pending work is flushed before shutdown
-  begins. `CancelTaskFrame` and `InterruptionTaskFrame` remain immediate
-  (`SystemFrame`).
-  (PR [#4006](https://github.com/pipecat-ai/pipecat/pull/4006))
-
-- Fixed `ParallelPipeline` dropping or misordering frames during lifecycle
-  synchronization. Buffered frames are now flushed in the correct order
-  relative to synchronization frames (`StartFrame` goes first,
-  `EndFrame`/`CancelFrame` go after), and frames added to the buffer during
-  flush are also drained.
-  (PR [#4007](https://github.com/pipecat-ai/pipecat/pull/4007))
-
-- Fixed `TTSService` potentially canceling in-flight audio during shutdown. The
-  stop sequence now waits for all queued audio contexts to finish processing
-  before canceling the stop frame task.
-  (PR [#4007](https://github.com/pipecat-ai/pipecat/pull/4007))
-
-- Fixed `Language` enum values (e.g. `Language.ES`) not being converted to
-  service-specific codes when passed via
-  `settings=Service.Settings(language=Language.ES)` at init time. This caused
-  API errors (e.g. 400 from Rime) because the raw enum was sent instead of the
-  expected language code (e.g. `"spa"`). Runtime updates via
-  `UpdateSettingsFrame` were unaffected. The fix centralizes conversion in the
-  base `TTSService` and `STTService` classes so all services handle this
-  consistently.
-  (PR [#4024](https://github.com/pipecat-ai/pipecat/pull/4024))
-
-- Fixed `DeepgramSTTService` ignoring the `base_url` scheme when using `ws://`
-  or `http://`. Previously these were silently overwritten with `wss://` /
-  `https://`, breaking air-gapped or private deployments that don't use TLS.
-  All scheme choices (`wss://`, `https://`, `ws://`, `http://`, or bare
-  hostname) are now respected.
-  (PR [#4026](https://github.com/pipecat-ai/pipecat/pull/4026))
-
-- Fixed `LLMSwitcher.register_function()` and `register_direct_function()` not
-  accepting or forwarding the `timeout_secs` parameter.
-  (PR [#4037](https://github.com/pipecat-ai/pipecat/pull/4037))
-
-- Fixed empty user transcriptions in Nova Sonic causing spurious interruptions.
-  Previously, an empty transcription could trigger an interruption of the
-  assistant's response even though the user hadn't actually spoken.
-  (PR [#4042](https://github.com/pipecat-ai/pipecat/pull/4042))
-
-- Fixed `SonioxSTTService` and `OpenAIRealtimeSTTService` crash when language
-  parameters contain plain strings instead of `Language` enum values.
-  (PR [#4046](https://github.com/pipecat-ai/pipecat/pull/4046))
-
-- Fixed premature user turn stops caused by late transcriptions arriving
-  between turns. A stale transcript from the previous turn could persist into
-  the next turn and trigger a stop before the current turn's real transcript
-  arrived. Stop strategies are now reset at both turn start and turn stop to
-  prevent state from leaking across turn boundaries.
-  (PR [#4057](https://github.com/pipecat-ai/pipecat/pull/4057))
-
-- Fixed raw language strings like `"de-DE"` silently failing when passed to
-  TTS/STT services (e.g. ElevenLabs producing no audio). Raw strings now go
-  through the same `Language` enum resolution as enum values, so regional codes
-  like `"de-DE"` are properly converted to service-expected formats like
-  `"de"`. Unrecognized strings log a warning instead of failing silently.
-  (PR [#4058](https://github.com/pipecat-ai/pipecat/pull/4058))
-
-- Fixed Deepgram STT list-type settings (`keyterm`, `keywords`, `search`,
-  `redact`, `replace`) being stringified instead of passed as lists to the SDK,
-  which caused them to be sent as literal strings (e.g. `"['pipecat']"`) in the
-  WebSocket query params.
-  (PR [#4063](https://github.com/pipecat-ai/pipecat/pull/4063))
-
-- Fixed `MinWordsUserTurnStartStrategy` including text below the word threshold
-  in the output by resetting aggregation when the minimum word count is not
-  met.
-  (PR [#4064](https://github.com/pipecat-ai/pipecat/pull/4064))
-
-- Fixed audio overlap and potential dropped TTS content when multiple assistant
-  turns occur in quick succession. `TTSService` now flushes remaining text
-  before pausing frame processing on `LLMFullResponseEndFrame`/`EndFrame`,
-  instead of pausing first.
-  (PR [#4071](https://github.com/pipecat-ai/pipecat/pull/4071))
-
-### Security
-
-- Bumped PyJWT minimum version from 2.10.1 to 2.12.0 in the `livekit` extra to
-  address CVE-2026-32597 (GHSA-752w-5fwx-jx9f), where PyJWT <= 2.11.0 accepted
-  unknown `crit` header extensions.
-  (PR [#4035](https://github.com/pipecat-ai/pipecat/pull/4035))
