Add keyterms and no_verbatim to Scribe realtime API

[kraenhansen]

Summary

• Add keyterms option (list[str]) to bias the Scribe model towards specific terms. Passed as repeated query params on the WebSocket URL.
• Add no_verbatim option (bool) to remove filler words, false starts, and disfluencies from transcripts.
• Both options added to RealtimeAudioOptions and RealtimeUrlOptions TypedDicts and threaded through to _build_websocket_url.

Python equivalent of elevenlabs/elevenlabs-js#376.

Test plan

• Unit tests for keyterms repeated query params
• Unit tests for no_verbatim true/false query param
• Unit test confirming params omitted when not specified
• All files edited are in .fernignore (hand-maintained)
• All 17 tests pass
• Manual verification with a real Scribe realtime session using keyterms
• Manual verification with no_verbatim=True

Note

Low Risk
Only adds optional query parameters and tests, with minimal impact on existing behavior unless callers start supplying the new options.

Overview
Extends Scribe realtime connection options with keyterms (list of bias terms) and no_verbatim (boolean transcript cleanup) for both manual-audio and URL-streaming modes.

Threads these values through connect() into _build_websocket_url, encoding keyterms as repeated keyterms=<term> query params and no_verbatim as a lowercased boolean when provided, and adds unit tests verifying correct inclusion and omission.

Looks good, but that bugbot comment should be addressed.
