This commit resolves the "download entire voices" issue by properly handling
absolute paths in Piper model configuration and improves the deployment system.
Key changes:
- speech.py: Detect absolute paths and omit --data-dir/--download-dir flags
when using absolute model paths, allowing Piper to load models directly
- speech.py: Add debug logging and stderr capture for Piper subprocess
- voice_to_speaker.default.yaml: Use absolute paths for all Piper models
- Makefile: Load deployment config from vars.sh for better security
- Makefile: Change restart to rebuild container ensuring code updates apply
- Add vars.sh.example template for deployment configuration
- .gitignore: Add vars.sh to prevent committing deployment secrets
Tested successfully with en_US-libritts_r-medium model using absolute path:
/app/voices/en/en_US/libritts_r/medium/en_US-libritts_r-medium.onnx
