Migrate from pytest-style to unittest.IsolatedAsyncioTestCase to match the
pattern used by other transport tests (e.g. test_livekit_transport.py). Guard
the aiortc/av import with try/except and skipUnless so tests gracefully skip
when webrtc dependencies aren't installed. Add pyright suppressions for false
positives inherent to testing internals of optional-dependency classes.

NLTK's sent_tokenize() only supports ~15 European languages and defaults to
English. For Japanese, Chinese, Korean, Hindi, Arabic, and other non-Latin
languages, NLTK fails to recognize sentence boundaries like 。？！ causing
text to accumulate until flush instead of being emitted sentence-by-sentence.
Add a fallback in match_endofsentence() that scans for unambiguous non-Latin
sentence-ending punctuation when NLTK fails to split the text. Latin
punctuation (. ! ? ; …) is excluded from the fallback since NLTK handles
those correctly and they can be ambiguous (abbreviations, decimals, etc.).

Incorporates latest changes from main branch including:
- AIC filter and VAD updates
- STT service improvements
- Base serializer changes
- Various bug fixes
If we aggregate transcriptions we will get incorrect interruptions. For example,
if we have a strategy with min_words=3 and we say "One" and pause, then "Two"
and pause and then "Three", this would trigger the start of the turn when it
shouldn't. We should only look at the incoming transcription text and don't
aggregate it with the previous.
* Krisp VIVA SDK Filter and Turn support.
* Reverted the krisp_filter.py as it's already deprectaed.
* enabled test with krisp_audio mock.
* More review comment fixes.
reverted the state logic in viva filter to be similar to the existing impl on main branch.
Fixed tests, ruff, etc.
* More review comments for Turn detection.
removed integration tests.
* Moved the SDK init/deinit into start/stop
