Workspace auto-saves every 30s and on exit, restores all tabs on
launch. Sessions persist drawing elements, SVG source, canvas state,
and metadata to ~/Library/Application Support/agcanvas/workspace.json.
Manual save via Cmd+S.
Command palette (Cmd+K) with fuzzy search over all commands: session
management, tool switching, view toggles, canvas operations. Arrow
keys to navigate, Enter to execute, Esc to dismiss.
Sessions now track who created them (Human vs Agent with name),
optional descriptions, and creation timestamps. Agents can create
and update sessions via WebSocket and MCP. ListSessions supports
sorting by name, created_at, created_by, or element_count.
New MCP tools: create_session, update_session. Updated list_sessions
with sort_by/sort_order params. Tab bar shows robot icon for
agent-created sessions with hover tooltips.
