- Remove .pmomusic.yml from git tracking (contains passwords)
- Add .pmomusic.yml.example as template without sensitive data
- Add SECURITY_CONFIG.md with setup instructions
- Credentials should be configured locally or via environment variables
This change prevents accidental exposure of Qobuz credentials.
Users must copy .pmomusic.yml.example to .pmomusic.yml and
configure their own credentials.
