merge: AgentProject membership — the junction is now load-bearing

Merges feat/agent-project-membership (task 166/152). An agent can finally join
many projects: membership routes, per-membership role and optional brain
override, chat resolving context from the membership, and CLI attach-agent /
detach-agent / get memberships. The legacy Agent.projectId fallback is kept for
this release as the schema comment promises.

Conflict resolved in main.ts: that branch added its RBAC case to
mapUrlToPermission inline, while this branch had extracted the function to
middleware/url-permission.ts so it could be tested. Kept the extraction and
ported the case into it — joining a team is `edit:agents:<name>`, not
`create:agents`, which is the authority to mint a whole agent.

Also fixes something the extraction makes possible. security.test.ts contained a
hand-copied reproduction of mapUrlToPermission, because main.ts self-invokes
main() and nothing in it was importable. A security test asserting against a
copy stops testing the system the moment the real one changes, and this copy had
already drifted. It now imports the real function; all 18 assertions still pass,
against the code that actually runs.

Local: build clean, workspace 2550 passed, lint unchanged at 794 errors.

+# Task ID: 26
+
+**Title:** Add HTTP REST server to mcplocal
+
+**Status:** done
+
+**Dependencies:** 25 ✓
+
+**Priority:** high
+
+**Description:** Add a Fastify HTTP server to mcplocal that runs alongside the existing stdio server, providing REST endpoints for mcpctl management commands.
+
+**Details:**
+
+1. Add Fastify dependency to mcplocal package.json: `@fastify/cors`, `fastify`
+2. Create `src/mcplocal/src/http/server.ts` with Fastify app setup:
+   ```typescript
+   import Fastify from 'fastify';
+   import cors from '@fastify/cors';
+   
+   export async function createHttpServer(config: HttpServerConfig) {
+     const app = Fastify({ logger: true });
+     await app.register(cors, { origin: true });
+     // Register routes
+     return app;
+   }
+   ```
+3. Create `src/mcplocal/src/http/routes/` directory structure
+4. Create health check endpoint: `GET /health`
+5. Create config types in `src/mcplocal/src/config.ts`:
+   - `httpPort`: number (default 3200)
+   - `httpHost`: string (default '127.0.0.1')
+   - `mcpdUrl`: string (default 'http://localhost:3100')
+6. Update mcplocal entry point to start both servers:
+   - stdio server for Claude MCP protocol
+   - HTTP server for mcpctl REST API
+7. Add graceful shutdown handling for both servers
+
+**Test Strategy:**
+
+1. Unit test: HTTP server starts on configured port
+2. Unit test: Health endpoint returns 200 OK
+3. Integration test: Both stdio and HTTP servers can run simultaneously
+4. Test graceful shutdown stops both servers cleanly
+5. Test CORS headers are present on responses
+6. Manual test: curl http://localhost:3200/health
