* Add Site Studio canvas extension
Site Studio is a canvas extension for planning, drafting, and tracking a
personal website section by section. It gives you and your agent a shared
dashboard with a status board, an autosaving content editor (with AI-draft
and [Sample: ...] placeholders), and a live feed of every change and milestone.

* Address Copilot review feedback
Robustness, prototype-pollution safety, and accessibility fixes from the
Copilot code review on #2117:
- Add "ai_request" to VALID_CHANGE_TYPES so log_change accepts the change
type the server itself emits (e.g. /api/request-generation).
- Bound the git branch lookup with timeout + maxBuffer so a hung git can't
block the extension process and canvas UI.
- Serialize state persistence via a promise queue and snapshot state
synchronously, so concurrent mutations can't clobber newer state on disk.
- Enforce a maximum request body size in readBodyJson to avoid unbounded
memory use on the loopback server.
- Guard the /events handler against a missing/closed instance instead of
throwing when servers.get(instanceId) is undefined.
- Reject unsafe field names (__proto__, prototype, constructor) in
upsertSectionContent and use an own-property check in deleteSectionContent
to prevent prototype pollution.
- Make the "Generate with AI" info tooltip reachable by keyboard and screen
readers (focusable, labelled) instead of mouse-hover only.
