* Add Java Modernization Studio canvas extension
A canvas extension that drives the GitHub Copilot App Modernization for Java workflow from an interactive dashboard: environment readiness checks, repo assessment, prioritized plan/progress, validation gates (CVE scan, test generation), and one-click predefined-task runs — all grounded in the repo's real artifacts (.appmod/assessment.json, plan.md, progress.md). Includes a node:test suite (109 tests) for the grounding logic.

* Secure cockpit loopback server with a per-instance token
Address Copilot review feedback on the Java Modernization Studio canvas:
- Mint a per-instance secret in createInstanceServer, embed it in the
iframe URL, and validate it on every loopback request (/, /state,
/events, /action). Other local processes can no longer read repo
state or dispatch agent actions just by guessing the random port.
Mirrors the existing diagram-viewer token pattern; the client echoes
the token from its boot payload. The guard is a no-op when no token is
set, so direct makeHandler unit tests are unaffected.
- Handle async request-handler rejections in createServer with a .catch
that returns 500 and logs, instead of leaking an unhandled rejection
that could destabilize the extension process.
- Tests: token guard 403s unauthenticated /, /state, /events and
/action and allows valid-token requests; the end-to-end test asserts
the tokenized URL and a tokenless 403.

* Fix CI: add preview screenshot and clear codespell hits
Add the required assets/preview.png screenshot for the canvas-extension
validator, and resolve two codespell findings in the cockpit:
rename the planSim helper's `nd` variable to `notDone` and reword a
catalog comment to avoid the `invokable`/`invocable` flag.

* Harden cockpit loopback server per Copilot review
Address the second-round Copilot review comments on the loopback server:
- broadcast(): drop an SSE client whose write() throws instead of keeping
it in the Set, so a uncleanly-disconnected client can't cause repeated
exceptions or leak dead entries on every subsequent broadcast.
- POST /action: treat a malformed JSON body or a missing/invalid "kind"
as a 400 client error (with an application/json body) instead of a 200
carrying { ok:false, error:"Unknown action: undefined" }.
- Handler catch: set Content-Type: application/json on the 500 error
response so it is consistent with the other JSON routes.
Adds four tests covering dead-client eviction, the two 400 paths, and the
JSON-typed 500. Full suite: 115 passing.

* Add canvas.json gallery metadata for Java Modernization Studio
Aaron requested a canvas.json so the awesome-copilot website/gallery can
list this extension. Generated via `npm run website:data`
(writePerExtensionCanvasManifests), which derives id/name/description/
version/keywords/screenshots from package.json + the createCanvas source +
assets, and carries the author through. Output committed verbatim so a CI
regeneration produces no diff.

* Add author tag to package.json
Declare the author in the package manifest (object form, matching the
author already carried in canvas.json so it includes the profile URL).
The published gallery sources author from canvas.json; this adds the
conventional npm author tag to package.json for completeness. Verified
`npm run website:data` still emits the author on the extensions record
and leaves canvas.json byte-identical.

* 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.
