Add MacOSPermissionsService (Dart) + native MethodChannel handler (Swift)
for macOS-specific permissions not covered by permission_handler:
- Input Monitoring (CGPreflightListenEventAccess /
CGRequestListenEventAccess) for global PTT via Event Tap
- Local Network Privacy prompt (NWBrowser for _ts3._tcp, macOS 15+)
- Notifications (UNUserNotificationCenter authorization)
Trace: SRS-198, SRS-297, SRS-300, SysRS-166, SDD-091
Changes:
- Info.plist: add NSBonjourServices array with _ts3._tcp
- macos_permissions_service.dart: Dart service with MethodChannel,
ValueNotifier states, PTT capability derivation (L0Focused /
L1MacOSEventTap), non-macOS short-circuit
- MainFlutterWindow.swift: native handler registered as FlutterPlugin,
Input Monitoring check/request/polling, NWBrowser trigger with
denial detection, UNUserNotificationCenter request
- main.dart: wire service into bootstrap lifecycle, listen for PTT
capability changes from Input Monitoring state
- macos_permissions_service_test.dart: 17 unit tests covering inbound
state changes, outbound calls, lifecycle, error handling, platform
behavior (179/179 full suite pass)
Clarify ONNX Runtime guidance with direct-open install hints, restore desktop WebRTC VAD visibility, map mouse side buttons through focused PTT capture/runtime paths, and wait for server acks before showing chat sends as successful.
Constraint: Linux release UX must stay functional when ONNX Runtime is optional and GNOME portal availability varies
Rejected: Keep desktop VAD locked to Silero only | misleads users when ONNX Runtime is skipped
Confidence: medium
Scope-risk: moderate
Directive: Preserve the protocol send-ack wait path for chat so UI success always tracks real server acceptance
Tested: flutter analyze lib/main.dart lib/widgets/chat_views.dart lib/widgets/input_dialogs.dart lib/widgets/startup_dependency_screen.dart; flutter test test/widgets/input_dialogs_test.dart test/widgets/chat_views_test.dart test/services/startup_dependency_check_test.dart test/widgets/startup_dependency_screen_test.dart test/widgets/voice_settings_controls_test.dart test/widgets/audio_processing_config_state_test.dart; cargo test -p chanora_protocol --lib; cargo test -p chanora_audio ptt_backends --lib
Not-tested: Live manual GNOME portal rebind/global PTT on a real desktop session; observer-bot chat against a live server after the sender-name fallback change
