#4415 chore: apply review notes from #4406, #4408 and #4410

Summary

• Apply the remaining reviewer notes from #4406, #4408, and #4410 across nine files: test raw annotation sizing and fitting, clarify relaunch recovery, and document Apple device ranking.
• No scope expansion. All substantive notes were applicable; prior-PR thread resolution and pre-merge instructions were already superseded by those merges.

Validation

• Base: 972451e2a7b06f986587ee55dfc4e084f477dbf3; head: ae6e769ff0949baf3c0a635887e61605502f8b43.
• pnpm check:affected --run --head ae6e769ff0: passed, receipt run-aaur50, exactCommit: true.
• Focused suites: 125 tests passed. The direct serializer suite passed 51 tests after its final edit.
• Isolated sizing mutation: the selector suite passed 20 tests on base with the updated test; sizing against verified instead of unverifiable failed the sweep at label length 179 (19 passed, 1 failed). The disposable checkout was removed.
• Integration and coverage are GitHub-owned; no device run was requested. An independent reviewer was unavailable; the diff was self-reviewed.
