Subject: [PATCH] fix: prevent unmanaging maximized/fullscreen windows on
 UnmapNotify

- Modify handle_unmap_notify in src/main.c to ignore UnmapNotify events
  for windows with CLIENT_MAXIMIZED or CLIENT_FULLSCREEN flags.
- This prevents browsers and other applications from becoming 'lost'
  (unmanaged but mapped) when they temporarily unmap themselves during
  state transitions or resizing.
