Subject: [PATCH] fix: reap child processes to prevent zombies and fix UTF-8
 title truncation

- Add go cmd.Wait() after cmd.Start() in launch() to reap child processes,
  preventing zombie accumulation on every app close
- Replace byte-based title truncation with rune-based truncation in
  clientMenu() and clientMenuContext() to avoid splitting multi-byte
  UTF-8 characters (e.g. CJK), which caused Pango invalid UTF-8 warnings
  and rendered as boxes in the right-click menu
- Remove commented-out non-ASCII stripping workaround that was a previous
  attempt to fix the truncation issue
