fix(mcp-discover): add updatedAt timestamp and connect MCP immediately after config write

- Add updatedAt: new Date().toISOString() when writing MCP server to config so
  clients can detect config changes without restarting
- Call MCP.connect(name) immediately after addMcpToConfig so the server becomes
  active in the current session — /mcps now shows connected without restart
