- Add if (!this.shadowRoot) guard in history panel and space settings
connectedCallback to prevent error on element reconnection
- Null-check toggleMemoryBtn before addEventListener since #toggle-memory
element was removed
- Import and register RStackSpaceSettings + RStackHistoryPanel in
canvas.html so settings gear and history panel work on canvas page

Move settings gear to header right (next to identity) on all pages.
Add history clock button in header left that opens a new slide-out
history panel with Activity feed and Time Machine tabs. Embed author
identity (DID, username, timestamp) in Automerge change messages via
JSON envelope, with backward-compatible parsing for old plain strings.
