fix(mlx): point Qwen 0.6B at the published mlx-community repo

Browse Source 
The 0.6B slot was aliased to the 1.7B repo as a temporary fallback
because `mlx-community/Qwen3-TTS-12Hz-0.6B-Base-bf16` wasn't published
when MLX support shipped. That conversion is live now, so use it —
Apple Silicon users picking 0.6B get the actual 0.6B model (1.2 GB
instead of 3.5 GB).

Also drops the now-obsolete troubleshooting entry and updates the
triage notes in PROJECT_STATUS.md.

Fixes #485.
