Problem: Scribe was failing on Slovenian narodno-zabavna songs (Avseniki,
Modrijani) because:
- User doesn't manually pick language (everything is auto)
- Scribe auto-detect had low confidence (0.58) on harmonika-heavy polka
- Result: only 37s transcribed instead of full 186s song
Solution: detect_language_from_filename() function:
- Recognizes 60+ Slovenian artists (Avseniki, Modrijani, Veseli Dolenjci, ...)
- Recognizes 30+ German artists (Ben Zucker, Helene Fischer, ...)
- Recognizes 20+ Croatian/Serbian artists (Thompson, Severina, Lepa Brena, ...)
- Falls back to keyword matching (volim, liebe, srce, herz, ...)
- Detects character set (č/ž/š → SL, ä/ö/ü/ß → DE, đ → HR)
- Score-based: 5pts for artist match, 1-2pts for keywords/chars
When detected, sends language_code to Scribe explicitly:
- Avseniki → 'slv' lock → no more half-transcribed songs
- Ben Zucker → 'deu' lock → consistent German transcription
- User still doesn't need to manually pick anything
filename_hint flows: main.py → analyze.py CLI → transcribe_full → Scribe
