Reorganize examples into topic-based subfolders
Move 304 examples from a flat numbered directory into 14 descriptive subfolders: getting-started, services (speech + function-calling), transcription, vision, realtime, persistent-context, context-summarization, update-settings (stt/tts/llm), turn-management, thinking-and-mcp, transports, video-avatar, video-processing, and features. Strip numbered prefixes from filenames (e.g. 07c-interruptible-deepgram.py becomes services/speech/deepgram.py) since the folder context makes them redundant. Keep numbered prefixes only in getting-started/ where ordering matters. Update eval script paths and README to match the new structure.

"""Example demonstrating advanced context summarization configuration.
|
||||
|
||||
This example shows how to customize context summarization with:
|
||||
- A dedicated cheap/fast LLM for generating summaries (Gemini Flash)
|
||||
- A custom summary message template (XML tags)
|
||||
- A custom summarization prompt
|
||||
- A summarization timeout
|
||||
- The on_summary_applied event for observability

"""Example demonstrating manual context summarization via a function call.

This example shows how to trigger context summarization on demand rather than

automatically. The user can ask the bot to "summarize the conversation" and the
|

bot will call a function that pushes an LLMSummarizeContextFrame into the

Unlike example 54, automatic summarization is NOT enabled here. Summarization

only happens when the user explicitly requests it through the function call.
