Add log level system and sync logging

- log.go: log level system (DEBUG, INFO, WARN, ERROR, NONE)
- CLI: -log-level flag (default info), -verbose as shorthand for debug
- Watcher: logs sync/remove actions at INFO level
- Watcher: logs events at DEBUG level
- Errors: structured error messages (DISK FULL, PERMISSION DENIED, etc.)
- Updated README with -log-level flag
