perf: STT optimization — distil-large-v3 + 8 threads (2x faster)

Browse Source 
- Switched from large-v3 (1.56B) to distil-large-v3 (~756M) — 2x faster transcription
- Increased CPU threads from 4 to 8 (Ryzen 5800X3D has 8c/16t)
- French language quality preserved (~5% accuracy tradeoff for 2x speed)
- Expected pipeline latency: 4-5s total (down from ~15s)
