chore: phase 1 cleanup — proper shutdown, flow resource cleanup, test fix

- node_runner: track all readers/writers in flow_resources vector,
  release them via mxlReleaseFlowWriter/mxlReleaseFlowReader before
  destroying the MXL instance (fixes 'leaked flow writer' warning)
- node_runner: remove_writer/remove_reader commands now also release
  the MXL flow resources, not just reset the node's optional<>
- engine: call process_manager.stop_all(graph) on shutdown to kill
  child node processes (prevents orphaned passthrough processes)
- graph: add get_node_mut() for process_manager to update node state
- process_manager: implement stop_all(Graph&) that SIGTERMs all
  running node processes
- passthrough: reduce logging to first-grain and realign-once only
- tests: update flow format assertion to match NMOS
  (urn:x-nmos:format:video instead of video/v210)

fix: engine REST API - handle GET/DELETE requests immediately, use user-provided node IDs

- Use lws_http_get_uri_and_method() for proper HTTP method detection
  (GET, POST, PUT, DELETE all supported)
- Handle GET/DELETE in LWS_CALLBACK_HTTP without waiting for body
- Support user-provided node IDs via config.id field
- Fixes all REST API endpoints hanging on GET requests

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)
