feat: add node HTTP control, engine-to-node communication, connect-input/output API

- Node control server now accepts HTTP POST /cmd for command dispatch
  (in addition to existing WebSocket control)
- Added NodeControlClient: engine sends commands to nodes via HTTP POST
- New REST endpoints:
  POST /api/graph/nodes/:id/connect-input  - connect node input to MXL flow
  POST /api/graph/nodes/:id/connect-output - create new MXL flow + connect output
  POST /api/graph/nodes/:id/disconnect-port - remove reader/writer
  POST /api/graph/nodes/:id/command - send raw command to node
- Flow IDs now use proper UUID v4 format (MXL requires standard UUIDs)
- Flow definitions use NMOS format (urn:x-nmos:format:video)
- Engine passes --mxl-domain to node processes
- User-provided node IDs (via 'id' field in POST body)
- End-to-end verified: testsrc → passthrough → new MXL output flow

fix: WebSocket control server - add HTTP mount for WS upgrade negotiation

LWS v4.x requires an HTTP mount with LWSMPRO_CALLBACK to properly
route WebSocket upgrade requests to the dmf-control protocol handler.
Without this, WS connections were rejected with 403 Forbidden.

feat: scaffold project framework with engine, node skeleton, and passthrough node

- CMake build system with vcpkg dependency management
- libdmf-node: Node interface, port definitions, WebSocket control
  server, node runner with MXL lifecycle management
- libdmf-engine: Graph model (nodes/edges CRUD, serialization),
  FlowManager (UUID + V210 NMOS flow definitions), ProcessManager
  (fork/exec node processes), ApiServer (REST API for graph control)
- Passthrough node: reads V210 grains from MXL, copies, writes to MXL
- Unit tests for Graph and FlowManager (6 cases, 21 assertions)
- MXL SDK as git submodule (symlinked from extern/mxl)
