docs(testing): add an RC end-to-end computer-use checklist

[EtienneLescot]

Summary

Turns the maintainer's informal pre-1.5 manual testing checklist (source/audio/editor/timeline/persistence smoke test) into a durable doc at docs/testing/rc-e2e-checklist.md, extended with everything shipped since that a unit/browser test can't exercise: native window capture vs. display-only, stop reliability with all extras disabled, HUD drag tracking, playhead sync during playback, auto-zoom cursor-following, Full Camera, and export-audio verification.

Each new item is phrased as an explicit regression check against the issue it guards (#60, #115, #100, #111, #72, #108), so a future run makes clear why that step exists, not just what to click.

Meant to be run top to bottom against a release candidate via the computer-use workflow already documented in AGENTS.md § Desktop E2E testing with computer-use. Includes a results log at the bottom to track which build was tested and what was found.

Doc-only change, no code touched.

- Line 31: Make the `#115` stop-completion checklist item explicitly Windows-only
and require execution on Windows; update docs/testing/rc-e2e-checklist.md lines
31-31 accordingly. Add an OS/platform column to the results log table at
docs/testing/rc-e2e-checklist.md lines 98-100 so each recorded result identifies
its test platform.
- Line 20: Update the “reproduce twice” guidance in the testing checklist so
intermittent behavioral bugs require two reproductions when practical, while
crashes, hangs, data loss, and security issues are always logged after the first
occurrence with reproduction details.
- Line 43: Update the system audio verification checklist item to require two
separate recordings with opposite toggle states—one enabled and one disabled—and
verify playback matches the corresponding state for each recording.
