Add FT-991A Remote Control App for macOS
Complete Phase 1 implementation of the Yaesu FT-991A remote control application with CAT protocol support over USB serial (CP210x). Features implemented: - SerialPortManager with auto-detection of CP210x ports - Full CAT protocol parser and command builder - RadioState model with all transceiver parameters - Modern SwiftUI interface with frequency/mode/level controls - Skeuomorphic front panel view (switchable) - Debug panel with CAT command console - QSO log panel with CSV export/import - Audio routing panel with BlackHole integration - Settings with connection, UI, keyboard configuration - Menu bar extra for background operation - German/English localization - Logging system for debugging Supports: Frequency control, VFO A/B, all modes (LSB/USB/CW/FM/AM/ DATA/RTTY/C4FM), level controls, NB/NR/DNF/ATU/Split functions, S-meter/Power/SWR metering, PTT control via Shift key. Target: macOS 15.0+ (Sequoia/Tahoe)
