docs(testing): log the 2026-07-19b/c RC follow-up passes on rc.3

[EtienneLescot]

Summary

Two follow-up passes on the docs/testing/rc-e2e-checklist.md RC checklist for v1.7.0-rc.3, continuing from the 2026-07-19 Windows pass already logged in the Results log:

• 2026-07-19b: automated-only pass (typecheck, lint, unit/browser/e2e tests, i18n:check, code review of the 10 commits unique to the rc.3 window) — no computer-use/GUI tool was available in that environment, so none of the manual checklist items could be re-verified live.
• 2026-07-19c: full computer-use/GUI pass against the real signed v1.7.0-rc.3 packaged .dmg (not a dev build), closing nearly every gap left open by the prior passes.

Findings

• macOS issue [Bug]: Crash after stopping macOS recording; MP4 and cursor metadata are written successfully #21 (shutdown-path crash) does not reproduce across 4+ rapid record→stop cycles against the packaged build.
• Two new bugs found and filed (not fixed in this PR — docs only):
  • #129 — npm run i18n:check fails with ~50 missing/extra translation keys; confirmed pre-existing debt, not an rc.3 regression.
  • #130 — windows-native-checklist.spec.ts references two testids that don't exist anywhere in LaunchWindow.tsx; the spec has apparently never actually executed since it self-skips off-Windows and CI is Linux-only.
• Corrected a wording issue in the checklist itself: there is no "highlight" cursor mode in the codebase — the real toggle is editable-overlay vs system.
• Remaining open gaps (tray icon stop, webcam mirroring/reactive zoom, macOS Spaces switch) are blocked by environment/hardware limits in this pass, not reproduced defects — noted inline for the next tester.

Targeted at main per the release-branch-freeze contract in .harness/docs/git-workflow.md (docs don't need cherry-picking to the release branch).

Summary by CodeRabbit

• Documentation
  • Updated the release-candidate end-to-end testing checklist with newly verified and newly clarified macOS findings.
  • Added clearer audio guidance (tray stop-recording access limits, video import availability, and audibility/tooling constraints).
  • Revalidated webcam and timeline behaviors (cursor overlay telemetry terminology and auto-zoom coverage), and noted remaining items blocked by missing hardware.
  • Expanded the results log with automated-only macOS details, translation check failure information, and tracked gaps/issues (129, 130).

In `@docs/testing/rc-e2e-checklist.md`:
- Line 54: Update the checklist item title in the cursor telemetry section to
replace the obsolete “highlight/spotlight” terminology with “editable cursor
telemetry overlay,” while preserving the existing validation details and
behavior.
- Line 34: Correct the checklist entry so it does not mark the launch-window
video-opening criterion as passed based on the separate Open Studio flow. Leave
the launch-window criterion unchecked or split it into distinct items, and mark
only the HUD → Open Studio → editor empty state → Import Video File path as
verified; retain the missing-control/test discrepancy as an issue.
- Line 45: Update the system-audio-only checklist item to avoid claiming audible
playback based solely on the waveform spike. Either leave the playback item
unchecked or rename it to describe capture-signal evidence only, and retain the
supporting recording details without asserting verified audibility.
