Add ORLY_POLICY_PATH for custom policy file location

- Add ORLY_POLICY_PATH environment variable to configure custom policy
  file path, overriding the default ~/.config/ORLY/policy.json location
- Enforce ABSOLUTE paths only - relay panics on startup if relative path
  is provided, preventing common misconfiguration errors
- Update PolicyManager to store and expose configPath for hot-reload saves
- Add ConfigPath() method to P struct delegating to internal PolicyManager
- Update NewWithManager() signature to accept optional custom path parameter
- Add BUG_REPORTS_AND_FEATURE_REQUEST_PROTOCOL.md with issue submission
  guidelines requiring environment details, reproduction steps, and logs
- Update README.md with system requirements (500MB minimum memory) and
  link to bug report protocol
- Update CLAUDE.md and README.md documentation for new ORLY_POLICY_PATH

Files modified:
