docs(testing): log the v2.0.0-rc.13 computer-use e2e pass

[EtienneLescot]

Logs the Windows computer-use pass on v2.0.0-rc.13, scoped to the app changes since rc.8 (the last computer-use pass; the rc.13 row already logged covers the export path).

Result: Partial — 1 defect

The webcam shows its first frame when a clip is entered past the webcam's last frame from another clip. Two clips of one take (screen video 50.98 s, webcam 51.24 s, audio and clip 51.31 s): scrubbing from clip 2 to 51.2 s in clip 1 shows the screen's last frame (227b9b8 works) but the webcam's frame 0. Reproduced 2/2; correct from inside clip 1 or at 51.0 s.

Cause: open_and_seek_clip and seek_pair in crates/compositor/src/live.rs seek the webcam with seek_to and fall back to seek_to(0.0), while present_frame uses seek_to_or_last. Still on main. Paused scrub only, ~70 ms window per clip, so not a promote blocker in my view.

Passed

• Closing the editor leaves OpenScreen running with no window after a working session #961: closing the editor after a take (countdown overlay present) leaves 0 processes
• [Bug]: timeline lane hints advertise the default shortcut letter after a shortcut is rebound #966: empty-lane hints follow rebound keys (Q, J); Q adds a zoom
• Wordmark menu in French: one line per row, version unsplit
• Preview playback across a trim and a 1.5× region: no stall > 150 ms; end of clip holds screen and webcam
• Editor preview shows stale captions after switching projects #960/fix(preview): hand out no native view while the view for a new source is created #964: A → B → A preview pixel-identical
• [Bug]: a failed transcription shows the raw IPC error on the media card #968: OS-refused read shows the translated hint inline and in the toast
• GUI MP4 export 1752×1080 30 fps, audio/video within one frame

Driven with real OS input; observation through PrintWindow + CDP because computer-use screenshots were grey. Not run: no-camera HUD (#967), macOS HUD fix, tray, GIF, macOS/Linux.

Before / after behavior

• observed — Modified behavior in technical-documentation/testing/manual-e2e-checklist.md: Added a Windows v2.0.0-rc.13 results-log row. It reports the webcam’s first-frame fallback when seeking from another clip into the final ~70 ms of a clip, while same-clip seeking and seeking to an earlier time show the correct frame; it also records passed checks, additional observations, and untested areas.
