- Add setup_logging() returning a named 'qbit-maid' logger with
RotatingFileHandler (configurable size/backups) and a console handler
- Add log_torrent() helper for structured torrent context
- Replace basicConfig-based tor_log() with setup_logging()
- Remove redundant 'if self.use_log:' guards across qbit-maid.py,
qlist.py, qprocess.py, qlogging.py (level filtering handles it)
- Document new logging options in config.toml.example and README
