Agent Deck setup

Treat setup as three separate layers: daemon health, host transport, then folder assignment.

1. Run agent-deck status and check http://127.0.0.1:1110/health (or <mcp-url>/health from .agent-deck/use.json if present).
2. If the daemon is down, tell the user to run:
   • npm i -g agent-deck
   • agent-deck start --daemon
3. If the daemon is healthy but MCP tools are unavailable, repair the host transport:
   • Codex: verify the Agent Deck plugin is installed, enabled, and current. Its bundled .mcp.json must run agent-deck mcp-launch; reload or start a new task after changing the plugin. Run agent-deck setup --client codex to merge the Agent Deck bootstrap guidance into ~/.codex/AGENTS.md (or add --scope project for ./AGENTS.md). This command preserves content outside Agent Deck's markers and does not install the plugin.
   • Cursor / Claude: run agent-deck setup --client cursor|claude --start, then restart that host.
4. Check the folder assignment reported by agent-deck status. If it is missing or legacy, tell the user to run agent-deck use <deck> in that folder, then reload or retry MCP.
5. Once transport and assignment are valid, use the session skill and require get_session_binding followed by get_bound_deck.
6. Do not invent credentials, ports, or shell install pipelines. Keep guidance read-only; the user executes install and setup commands.
