Summary

On Linux, Instant draws the camera into the screen video, so a camera that stalls or sends a bad frame stops the recording. No CI case recorded Instant with a camera: Blacksmith's kernel cannot load v4l2loopback.

• New ignored real-app case real_app_instant_recording_with_camera_uploads_and_verifies, gated on CAP_GPUI_REAL_APP_CAMERA=1. It selects the first camera and records a full-screen window; X11 waits for the Stop shortcut before a camera window recording starts, so the case presses it to start and stop. It checks the upload verifies, the mock server confirms it, nothing is deleted and nothing panics.
• The Blacksmith Linux job now uploads its app and test binary. A hosted ubuntu-24.04 job loads v4l2loopback (with linux-modules-extra for videodev), feeds a 720p YUYV test pattern, runs the case, then joins the recorded segments and checks at least 95% of frames carry the pattern's colour. The recorded window is grey, so a frame without colour is a frame without the camera.
• The workflow also triggers on crates/camera, crates/camera-ffmpeg and crates/recording/src/instant_recording/.

Test plan

• Dispatched on this branch: 245 of 245 frames show the camera, upload verified
• Dispatched with perf(linux-camera): copy frames once #3146 merged on top: 247 of 247 frames, upload verified
• macOS real-app job skips the case (no camera on that runner)

Confidence Score: 5/5

The PR appears safe to merge; the previous filter issue is fixed.

Summary

Adds a Linux CI check that records Instant with a virtual camera and checks that its picture reaches the saved video.

• Linux CI records Instant with a camera and checks the saved video.
