START_INGEST carries stream_id, format/width/height/fps, dest_host:port,
transport_mode (encapsulated or opaque), and device_path. All format fields
default to 0 (auto-select). STOP_INGEST carries stream_id only.
Both commands set wanted state on the node; reconciliation is asynchronous.
Protocol doc updated with wire schemas for both commands.

- Protocol module: framed binary encoding for control requests/responses
(ENUM_DEVICES, ENUM_CONTROLS, GET/SET_CONTROL, STREAM_OPEN/CLOSE)
- video-node: scans /dev/media* and /dev/video*, serves V4L2 device
topology and controls over TCP; uses UDP discovery for peer announce
- query_cli: auto-discovers a node, queries devices and controls
- protocol_cli: low-level protocol frame decoder for debugging
- dev/web: Express 5 ESM web inspector — live SSE discovery picker,
REST bridge to video-node, controls UI with sliders/selects/checkboxes
- Makefile: sequential module builds before cli/node to fix make -j races
- common.mk: add DEPFLAGS (-MMD -MP) for automatic header dependencies
- All module Makefiles: split compile/link, generate .d dependency files
- discovery: replace 100ms poll loop with pthread_cond_timedwait;
respond to all announcements (not just new peers) for instant re-discovery
- ENUM_DEVICES response: carry device_caps (V4L2_CAP_*) per video node
so clients can distinguish capture nodes from metadata nodes
