* 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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.

Install a Plugin
For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:
copilot plugin install <plugin-name>@awesome-copilot
If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:
copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
