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)
