Issue 1: tapping Space in the PTT binding capture dialog set _captured to LogicalKeyboardKey.space.keyLabel which is ' ' (a single space character), rendering as a blank string in the 'Captured: ' display. Same problem for Enter, Tab, Backspace, etc. — Flutter's keyLabel returns the printable representation, not a readable name. Added _displayLabelForKey() with a table that maps whitespace and common special keys to canonical English labels matching the entries in crates/chanora_audio/src/ptt_backends/windows_keymap.rs (so the bridge resolves to the right VK_* on Windows). Pure modifier keys (shift / ctrl / alt / meta / caps / num / scroll lock) return null so they don't accidentally bind on their own. Issue 2: physical key press -> 'PTT=on' in the Voice Bar lagged by up to ~500 ms because audioStats was polled at 500 ms intervals. The Rust-side transition is microsecond-fast; the visible delay is purely the Flutter poll interval. Cut to 80 ms (~12 Hz), well below the perceptual lag threshold. Adds ~12 small FFI calls per second, trivially cheap. A push-based BridgeEvent::TransmitActiveChanged would let us drop the poll entirely; noted as a follow-up. flutter analyze: clean (6 pre-existing Radio.groupValue infos).
