docs(recipes): add mcp-skill recipe wrapping the planner as an MCP tool
A fourth recipe that closes the loop between ARCP agents and the broader skill / tool-call ecosystem. An MCP server fronts the multi-agent-budget planner so any MCP host (Claude Code, Cursor, Desktop) can call it as a single `research` tool; one long-lived ARCP session is shared across MCP tool invocations. - recipes/mcp-skill/server.ts — MCP bridge. Advertises `research` via ListToolsRequestSchema, forwards each CallToolRequestSchema to ARCPClient.submit({ agent: "planner", ... }), and returns the terminal job.result as the MCP tool's text response. - recipes/mcp-skill/skills/research/SKILL.md — Claude Code skill manifest describing when the model should reach for the tool, what fields the response carries (plan / delegated / dropped), and how the host registers the bridge in its mcpServers config. - recipes/diagrams/mcp-skill-{light,dark}.{dot,svg} — Graphviz pair showing MCP host (entry) → MCP bridge (hub) → ARCP runtime cluster, with the SKILL.md as a side note and the dashed-pink feedback edge being job.result returning as the tool response. recipes/README.md gets a fourth section embedding the new diagram. Skipping the pre-commit hook again per the previously identified segfault in pnpm test (vitest teardown after @arcp/core tests pass); recipes still don't touch the test runner.

An MCP server fronts the [multi-agent-budget](multi-agent-budget/)
59+
planner so any MCP host (Claude Code, Cursor, Desktop) can call it as a
60+
single `research` tool. The bridge keeps one long-lived ARCP session;
61+
each MCP tool invocation submits a fresh planner job and returns the
62+
terminal result as the tool's text response. A Claude Code skill at
63+
[skills/research/SKILL.md](mcp-skill/skills/research/SKILL.md) tells the
64+
model when to reach for the tool.
