New Features:
- Added command-line option for system volume following and a background thread that polls the default audio sink volume
- Integrated the polled volume multiplier into playback volume calculations
- Introduced new runtime states and flags for system volume tracking
Enhancements:
- Replaced scattered printf debugging with standardized LOG_ERROR/DEBUG/WARN macros
- Pre‑read all runtime states before spawning threads, simplifying the main loop
- Detached the poller thread to run continuously without blocking the main loop
Bug Fixes:
- Extended argument count validation to accommodate the new flag
- Updated thread creation error logging to use LOG_ERROR instead of fprintf
- Fixed potential race by initializing the volume multiplier before playback threads start
