Fix a desktop-session freeze (forced logout/reboot) caused by the overlay's
AT-SPI caret tracker: it subscribed to the high-frequency object:text-caret-moved
signal and made synchronous, blocking AT-SPI reads from inside the event handler,
re-entering the a11y dispatcher and getting stormed by the app's own xdotool
typing until GNOME stopped responding. Now track focus changes only and read the
caret rectangle lazily, once, when the overlay shows — never on the hot path.
Fuse voice-routing feedback into the overlay instead of a desktop notification:
show the matched preset's emoji, name, and spoken keyword on a banner, narrate
the phase (Transcribing -> Rewriting), and stream the LLM rewrite into the bubble
token-by-token. Redundant per-dictation notifications are suppressed when the
overlay is present (errors still notify); headless/overlay-off is unchanged.

Show a translucent, click-through bubble the moment recording starts (by
hotkey or wakeword): a pulsing microphone, a live waveform of the mic
level, and the recognised text (word-by-word when streaming, otherwise a
brief final-result confirmation). The tail points at the text caret via
AT-SPI accessibility, falling back to the mouse pointer, then a screen
corner. Also gives hands-free wakeword sessions visible feedback, whose
notifications are suppressed by design. X11 only.
- overlay.py: GTK override-redirect HUD (mic + waveform + bubble), drawn
with Cairo; thread-safe, marshalled onto the GTK loop.
- caret.py: best-effort anchor (AT-SPI caret -> pointer -> window/corner).
- daemon: optional level_cb/text_cb hooks; reuses the VAD level meter for
non-streaming, a dedicated meter for streaming. Stays UI-agnostic.
- gtkui: instantiate the overlay, drive show/update/hide from status.
- General settings: "Visual overlay" toggle; config overlay_enabled /
overlay_anchor (default on, "caret").
- Docs: CHANGELOG 1.5.0, version bump, README + MANUAL.
