When Whisper hallucinates (generates fake lyrics not matching the audio),
LLM can now use the original filename as a hint to recognize the song
and override the false transcript with the actual lyrics.
Pipeline:
1. Pass filename (e.g. 'Ben Zucker - Bonnie und Clyde') as hint
2. Whisper transcribes (may hallucinate)
3. Claude/Gemini reads filename + transcript:
- Recognizes song from filename hint
- Compares Whisper output to known lyrics
- Replaces hallucinated text with real lyrics (preserves timestamps)
- If can't fix, removes segment (better silent than wrong)
Also added Whisper anti-hallucination params:
- beam_size=5 (more careful decoding vs greedy)
- hallucination_silence_threshold=2.0 (skip text in long silences)
