MCP recording with camera: true has no webcam on Linux while the app is running #1303

On Linux, an MCP startRecording with camera: true produces a take with no webcam, and reports no error, while the app is running.

Found in the Linux pass of v2.1.0-rc.5 (#1302), on Ubuntu 24.04, GNOME 46 Wayland.

What happens

• The app keeps the webcam open, even with the HUD hidden.
• The MCP recording then gets no camera and the take is saved without one.
• Nothing tells the caller: the tool returns success.

Workaround: quit the app before recording through MCP.

Expected: the MCP take reuses the app's camera stream, or the tool fails with a clear error instead of silently dropping the camera.

Not a regression check yet: whether 2.0.0 does the same is not known.
