Refuse close requests on the pre-mapped Wayland overlay so closing its GNOME dock entry no longer destroys it and brings back the first-recording focus loss, and unmap the overlay when it is turned off so the dock entry goes away immediately.
Fixes#1010
* fix(overlay): map the dictation overlay at startup on Wayland
Mutter activates newly mapped Wayland toplevels, which can take focus from the editor.
Map the fallback overlay transparently at startup so its first recording does not remap it.
Fixes#992
* fix(overlay): detect the Wayland display by GType name for the prewarm
Detect Wayland from the display GType because GTK3 omits GdkWaylandDisplay from its typelib.
* feat(ui): add floating glowing dictation overlay
Show a bottom-center non-focus overlay while recognition is LISTENING
or PROCESSING so users get a clear visual cue beyond the tray icon.
Optional GtkLayerShell on Wayland; plain always-on-top GTK fallback
elsewhere. Configurable via ui.show_overlay (default on) and Settings.
* fix(test): isolate dictation overlay tests from GTK pollution
Overlay unit tests no longer construct real GTK windows or import
tray_indicator, which was loading gi.repository early and breaking
later tests that mock GI (single-instance and suspend GLib checks).
* docs: add dictation overlay screenshots
Capture the floating glowing orb in listening (green) and processing
(amber) states for the PR and README screenshots section.
* test(ui): raise dictation overlay coverage for Codecov patch gate
Exercise GTK init, draw/animation, positioning, layer-shell fallbacks,
tray overlay wiring, settings toggle, and config edge cases so patch
coverage on the floating overlay clears the 80% Codecov target.
* test(tray): call overlay helpers via unbound methods
Avoid instance-level MagicMock shadowing of set_overlay_enabled under
some import/mock orderings (seen on CI Python 3.10).
* test(tray): inject explicit config mock for overlay helpers
Assign a MagicMock config_manager on the instance so assertions do not
depend on the constructor patch (which can leave a real ConfigManager
under some Python versions / import orders).
* refactor(ui): ponytail pass on dictation overlay
Drop the hand-drawn mic glyph, simplify the Cairo clear/pulse path,
reuse ConfigManager get_bool/set, tighten tray overlay helpers, and
delete string-grep structural tests that proved nothing.
* fix(ui): pin overlay to bottom strip and stop stealing focus
Use a full-width bottom strip (layer-shell left/right/bottom anchors, or
resize+move fallback) so the orb is bottom-center on Wayland. Map the
window once and toggle opacity instead of hide/show so compositors do not
re-activate it and yank focus out of the editor (which broke IBus inject).
* fix(appimage): seed GtkLayerShell typelib for dictation overlay
* fix(ui): address greptile findings on dictation overlay
* fix(appimage): keep layer-shell typelib optional for direct builds
