Some TTS providers (e.g. Inworld) return verbatim tokens where spaces and punctuation are already embedded in the token text. When downstream consumers join these tokens with an extra space they produce "hello , world" instead of "hello, world". Add an opt-in `includes_inter_frame_spaces: bool = False` parameter to `add_word_timestamps` / `_add_word_timestamps`. The flag is threaded through `_WordTimestampEntry` and stamped onto every emitted `TTSTextFrame`. Defaults to `False` — no behaviour change for existing services. `InworldTTSService` passes `includes_inter_frame_spaces=True` and stops pre-processing tokens in `_calculate_word_times`, returning them verbatim. Tests added to `test_tts_frame_ordering.py` covering both HTTP and WebSocket delivery paths: verbatim text preservation, PTS ordering, text-before-audio ordering, and the Inworld punctuation-token scenario.
