feat: v1.2.0 — auto-reconnect, recording, monitor bounds, WASAPI loopback

- Auto-reconnect: stream retries with exponential backoff (2s→30s max)
  on unexpected exit; stops only when user clicks Stop
- Recording: global RecordingBar with folder picker, segment duration (min),
  per-stream checkbox, Select All; uses FFmpeg tee muxer for simultaneous
  SRT + segmented .ts file output
- Monitor capture: PowerShell System.Windows.Forms.Screen gives exact
  pixel bounds (x/y/width/height); per-monitor deviceName is now unique
  (desktop_monitor_N); gdigrab uses -offset_x/-offset_y/-video_size
- Window capture: windowTitle now explicitly propagated in handleVideoSelect
- System audio: added WASAPI Loopback option (no VB-Audio required),
  existing virtual-audio-capturer kept as fallback
- Reconnecting event forwarded to renderer; status shows "Reconnecting…"
  with attempt count in logs
- IPC: pick-folder (dialog.showOpenDialog) and open-folder (shell.openPath)
