Description

Fixes 7 typos in comments, JSDoc and two debug log strings. No logic changes.

• src/ui/alert/AlertController.ts (line 156): comment collpased -> collapsed
• src/ui/alert/AlertController.ts (line 171): comment within 2 sec of of mouseleave event -> within 2 sec of mouseleave event
• src/proxy/ChildContextInjector.ts (line 18): JSDoc maps iframe elements to its contentDocument -> their contentDocument (the antecedent elements is plural)
• src/messaging/InterContextMessageHub.ts (line 102): log.print('MesageHub: received a message from a port') -> MessageHub
• src/messaging/InterContextMessageHub.ts (line 147): log.print('MesageHub: sending a message to a port') -> MessageHub
• locales.ts (line 36): JSDoc Build query string for downloading tranlations -> translations
• locales.ts (line 49): JSDoc Build form data for uploading tranlation -> translation

The two InterContextMessageHub changes are the only ones that touch executable lines: they are the text
inside log.print(...) debug messages, and they are already spelled MessageHub on lines 50 and 56 of the
same file, so this only makes the log output self-consistent. Worth a careful look all the same, since they
are string literals rather than comments. I grepped the whole repository (including test/) for MesageHub:
the two lines changed here are the only occurrences, so no test assertions or other call sites depend on the
old spelling.

Testing Instructions

No runtime behaviour changes, so there is nothing to test functionally. git diff shows 7 changed lines
across 4 files, all inside comments or debug log strings.

Additional Notes

Two notes on your conventions, since I am an outside contributor:

1. AGENTS.md requires commit messages to start with an AG-XXX ticket number. I do not have a tracker
   ticket, so I used the Conventional Commits fallback the same section allows (docs:). Happy to reword or
   rebase if you would rather attach a ticket number.
2. I did not add a CHANGELOG.md entry, since nothing user-facing changed. Glad to add one if you prefer.

Not fixed here, but noticed on the same line as the ChildContextInjector change: Weakmap would more
conventionally be spelled WeakMap, matching the IWeakMap type on the next line. Left alone to keep this PR
to the verified set.
