Add native Windows and macOS screen/audio/webcam recording support

[Copilot]

Extends the Linux-only screen recorder to support Windows and macOS using platform-specific ffmpeg inputs.

Changes

Platform detection

• Added OS detection (OSWindows, OSDarwin, OSLinux) to deps package
• Display server detection (Wayland/X11) now Linux-only

Windows implementation (ffmpeg)

• Screen: gdigrab captures full desktop
• Audio: dshow with empty device name for auto-detection
• Webcam: dshow with empty device name for auto-detection

macOS implementation (ffmpeg)

• Screen: avfoundation device "1:none" (main display with cursor)
• Audio: avfoundation device ":0" (default microphone)
• Webcam: avfoundation device "0:none" (default camera)

Architecture

func (r *Recorder) Start() error {
    switch deps.DetectOS() {
    case deps.OSWindows:
        return r.startWindows()
    case deps.OSDarwin:
        return r.startMacOS()
    case deps.OSLinux:
        return r.startLinux()
    }
}

Each platform implements startVideo/Audio/Webcam methods with platform-specific ffmpeg arguments. Monitor detection returns placeholder data on Windows/macOS since ffmpeg handles actual resolution detection at runtime.

Limitations

• Windows/macOS: Single monitor support only (captures primary/all screens)
• Hardware acceleration remains Linux-only (VAAPI)
• macOS requires system permissions for screen/audio/camera access

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

well review the codebase here please and make a pr that adds support for windows and mac - specifically using native screen webcam and audio recording
