v1.3.2 - Quality of life fixes

What's fixed

Four quality-of-life fixes, three of them reported by real first-day usage of v1.3.1 thank you for the feedback! 🙏

• 👻 Ghost process on quit quitting from the tray could leave an invisible
  WritHer.exe alive, which kept the single-instance lock held: no tray icon, yet
  every new launch said "WritHer is already running". The process now always
  terminates cleanly, even if you quit while the model is still loading.
• 📏 Widget text no longer clipped the floating pill now grows to fit long
  messages ("Downloading speech model…", microphone errors, localized strings)
  instead of cutting them off at the edge.
• ⌨️ Startup hints match your recording mode if you use toggle mode, the
  ready message and welcome notification now say "press" instead of "hold".
• 🎯 Accurate "Downloading" vs "Loading" the startup status now checks the
  actual model cache on disk, so "Downloading speech model…" only appears when
  a download is really happening. Reminder: the model is downloaded once;
  every later launch just loads it from disk into memory (a few seconds).
