Note for reviewers:
This is a background daemon with a system tray icon, not a main GUI app.
The CI warnings (No windows on screen, missing DBus portal/StatusNotifierWatcher) are expected in a headless environment.

✅ AppImage launches successfully.
✅ Built on Ubuntu 22.04 → GLIBC compatibility fixed.
✅ Speech-to-text core functionality works as intended.
