* fix(mcp): sync browser state before get_diagram to prevent data loss

- Add syncRequested flag to SessionState for browser sync coordination
- Add requestSync() and waitForSync() functions to http-server
- Browser polls for syncRequested flag and immediately pushes current state
- get_diagram now syncs fresh state from browser before returning
- edit_diagram requires get_diagram to be called within 30s to prevent stale edits
- Updated edit_diagram description to enforce workflow

* fix(mcp): make lastGetDiagramTime session-scoped and handle missing session in requestSync

- Move lastGetDiagramTime into currentSession object to prevent cross-session issues
- requestSync now returns boolean indicating if request was made
- Only wait for sync if session exists (avoids false-positive from undefined state)
