**Server Implementation Requirements:**

**Endpoint**: \`initialize\`

**Requirements**:
- Accept \`initialize\` request with client info and capabilities
- Return valid initialize response with server info, protocol version, and capabilities
- Accept \`initialized\` notification from client after handshake

This test verifies the server can complete the two-phase initialization handshake successfully.`;
