Conflicts, all in apps/desktop/src/i18n:
- de/en/es/fr/zh.ts, types.ts: import blocks only. Main added the
*_projects section split, this branch the *_onboarding one; kept both.
- en_shared_metrics, zh_shared_metrics, ar_common, zh-hant (usage-stats
consent copy): kept this branch's rewritten copy. Main's only change on
its side since the merge base was a prettier reflow of
collectedReliability (2943ee6f19), which the branch's rewrite replaces;
types_shared_metrics on HEAD already matches the branch's keys.
Follow-through: main's Undo-hide toast (sidebar.projects.hiddenFromSidebar /
undoHide) arrived without ar or zh-hant strings, which this branch's
overlay-completeness test rejects. Added both to ar_chrome / zh-hant_chrome
and regenerated locales/_keys.desktop.json.
