- processUtterance runs on a detached std.Thread; Qt event loop stays
responsive during whisper/letta/melo (icon repaints, menu works)
- setState marshals to main thread via threading.async with thread-id check
- rapid double-click race guarded: state claimed before spawn
- icon: QPainter-drawn antialiased circle (dark rim, transparent bg) —
bare pixmap.fill rendered blank on the KDE SNI host
- new qt libs: qbrush, qpainter, qrect, qt6zigthreading
