Wayland screen capture not yet implemented.

Error message

Wayland screen capture not yet implemented.

What it means

Sentinel error: the Wayland client's screen_capture_sources immediately resolves with Err because screen capture is unimplemented on Wayland (see the TODO). It is not a runtime failure of an attempted capture; callers requesting screen-share sources on Wayland always get this.

Solutions

1. Implement Wayland screen capture via xdg-desktop-portal's ScreenCast interface (org.freedesktop.portal.ScreenCast)
2. Until implemented, callers should detect Wayland and disable/hide screen-share UI rather than invoking this API
3. The TODO notes window resizing of captured streams needs care once pipewire streams are wired up
