Complete C rewrite with instant hotkeys and stable monitor ordering

Major Changes

Complete native Win32 C implementation

• Replaced AutoHotkey with pure C — Single implementation using Win32 CCD APIs
• Zero dependencies — No AutoHotkey runtime required
• Faster startup and lower memory footprint
• Cross-compilation support from Linux via MinGW-w64

Instant monitor switching hotkeys

• Ctrl+Alt+1..9 — Switch directly to monitor N without confirmation dialog
• Dynamic registration — Hotkeys automatically adjust when monitors are connected/disconnected
• Improved synchronization — Hotkeys update correctly during physical monitor changes

Unified hotkey scheme

• All hotkeys now use Ctrl+Alt for consistency:
  • Ctrl+Alt+M — Show tray menu
  • Ctrl+Alt+R — Restore original configuration
  • Ctrl+Alt+H — Toggle HDR on primary monitor
  • Ctrl+Alt+1..9 — Switch directly to monitor N

Stable monitor ordering

• Port-centric sorting — Monitor order now matches Windows Settings exactly
• Predictable numbering — Same port always gets same hotkey (1, 2, 3...) regardless of activation order
• Based on Adapter LUID + Target ID — Hardware-level stable identifiers

Enhanced topology detection

• Smart restore behavior — "Restore original config" now works regardless of who changed the display topology (program vs Windows Settings)
• Real-time detection — Menu instantly reflects current topology state
• Improved debouncing — 2-second delay prevents race conditions during monitor enumeration

Technical Improvements

• Three-attempt display configuration — Fallback strategy prevents 60Hz downgrades
• Registry-based HDR state reading — More reliable than CCD API on some devices
• Balloon notifications — Integration with Windows 11 notification center
• Error feedback — Clear error messages for common failure scenarios
