src/node/main.c: ctrl_enum_cb was discarding menu_count and menu_items,
causing empty dropdowns for all MENU/INTEGER_MENU controls. Added a
menu item pool (MAX_MENU_POOL=128 items) to Ctrl_Build; the callback now
copies items into the pool and sets menu_count/menu_items on the control.
docs/protocol.md: add missing sections — str8 primitive, ENUM_DEVICES,
ENUM_CONTROLS (with control type/flag tables and menu item notes),
GET_CONTROL, and SET_CONTROL schemas.

- 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
