# Task ID: 144

**Title:** Session routes and exec/attach endpoints

**Status:** pending

**Dependencies:** 143

**Priority:** high

**Description:** Create Session routes with CRUD, one-shot exec, and WebSocket attach endpoints

**Details:**

Create src/mcpd/src/routes/session.routes.ts:
1. GET /api/v1/sessions - list with ?project=&agent=&task= filters
2. POST /api/v1/sessions - create and provision
3. GET /api/v1/sessions/:id - get
4. DELETE /api/v1/sessions/:id - end session
5. POST /api/v1/sessions/:id/exec - one-shot exec, body: { command: string[] }, returns { exitCode, stdout, stderr }
6. GET /api/v1/sessions/:id/attach - WebSocket upgrade, bidirectional stdio with terminal resize and exit code propagation
7. Use existing execInContainer, attachInteractive from orchestrator
8. Register in main.ts

**Test Strategy:**

Route tests: test CRUD, test exec returns command output, test attach upgrades to WebSocket. Integration: exec 'echo hello' in session pod, verify output.
