Displays logs for daemon(s)

Shows logs from managed daemons. Logs are stored in the pitchfork logs directory
and include timestamps for filtering.

Examples:
  pitchfork logs api              Show all logs for 'api' (paged if needed)
  pitchfork logs api worker       Show logs for multiple daemons
  pitchfork logs                  Show logs for all daemons
  pitchfork logs api -n 50        Show last 50 lines
  pitchfork logs api --follow     Follow logs in real-time
  pitchfork logs api --since '2024-01-15 10:00:00'
                                  Show logs since a specific time (forward)
  pitchfork logs api --since '10:30:00'
                                  Show logs since 10:30:00 today
  pitchfork logs api --since '10:30' --until '12:00'
                                  Show logs since 10:30:00 until 12:00:00 today
  pitchfork logs api --since 5min Show logs from last 5 minutes
  pitchfork logs api --raw        Output raw log lines without formatting
  pitchfork logs api --raw -n 100 Output last 100 raw log lines
  pitchfork logs api --clear      Delete logs for 'api'
  pitchfork logs --clear          Delete logs for all daemons"
