Kayshen-X a7d73ebb62 feat(ai): pencil-style agentic design tool-loop, multi-chat tabs, #27 panel restyle
Built-in design generation now runs as an agentic MCP tool-loop (reusing the
agent-rs BuiltInProvider), gated behind OPENPENCIL_DESIGN_AGENT_LOOP / the
Settings experimental toggle; the orchestrator stays the default.

- design-agent system prompt + in-process design toolset (parity-locked with
  the MCP surface) + flag-gated Intent::Design routing
- spawn_agents execution as sequential sub-loops + live creation-mode badges
  (per-agent glow + 'N/M designing...' header)
- new MCP tools: get_guidelines, ToolSearch, get_screenshot, get_editor_state,
  export_nodes, spawn_agents; style-guide local audit
- #27 AI panel restyle: rounded tool cards + green check-rings, gray user
  bubbles, model-pill bottom toolbar, header, empty-state pills, the
  PARALLEL AGENTS (agent_team_size) 1x-6x chip dropdown
- multi-chat tabs: ChatSessions model (Deref-to-active) + tab row UI
  (switch / close / + / Cmd+T) with each run bound to its tab

Large checkpoint commit spanning the working tree (Rust shell crates).
