Canvas extensions (accessibility-kanban, where-was-i) resolved git state
against the extension's install directory or the session-state folder
instead of the repo the session was opened in. This broke repo/branch
detection for user-scoped installs and worktrees ("unknown/unknown",
"detached HEAD"). Both now read the active session's working directory
from the canvas request context on open and on each action, so they
follow whichever project/worktree opened them.
where-was-i also re-gathers context on open when the saved branch is
blank, so it never opens stuck on stale data.
Also compress oversized extension preview images (pngquant, with a mild
resize for the photographic arcade-canvas art) so every preview.png is
comfortably under the installer's inline-byte cap that was blocking
release-notes-showcase from installing.
Update release-notes-showcase author to Kayla Cinnamon.

* Remove pluginRoots property from marketplace.json
The pluginRoots property is not used by install tooling and was only
informational about the extension/plugin source directories. Removing it
simplifies the marketplace.json structure while maintaining all functionality.

* Migrate java-modernization-studio to plugin.json and update validation workflow
- Create .github/plugin/plugin.json for java-modernization-studio extension
- Remove legacy canvas.json from java-modernization-studio
- Update validate-canvas-extensions.yml workflow to check for plugin.json instead of canvas.json
- Update workflow to trigger on .schemas/plugin.schema.json changes (instead of canvas.schema.json)
- Remove schema validation logic that relied on canvas.schema.json
- All 12 extensions now use plugin.json for metadata

* Add extensions field to all extension plugin.json files
Per https://github.com/github/copilot-agent-runtime/pull/9929, plugins that ship
extensions need to include an extensions field specifying where the extension code
is located. All 12 extensions now have extensions set to '.' to reference the
current directory where extension.mjs is located.

* Enforce convention-based extension metadata and remove x-awesome-copilot
- Remove x-awesome-copilot.screenshots from all extension plugin.json files
- Enforce logo=assets/preview.png convention for all extensions
- Enforce extensions=. per copilot-agent-runtime#9929
- Update validate-plugins.mjs to enforce conventions
- Update validate-canvas-extensions.yml workflow with convention checks
- Update AGENTS.md and CONTRIBUTING.md documentation
All 12 extensions validated successfully.

* Potential fix for pull request finding

* Use standard plugin validation for extensions
Remove the custom extension schema and schema validation helper, and
validate extension plugin.json files through the existing plugin validator
instead. Update workflows to stop depending on the removed schema.

* 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.
