Add protocol module, video-node binary, query/web CLI tools
- 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 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
