Makefile:
- Add reconciler and ingest to the `modules` target; they were only built
as side-effects of `make node`, making `make modules` incomplete
planning.md:
- Add 4 missing CLI drivers: discovery_cli, config_cli, protocol_cli,
query_cli (all existed in code and dev/cli/Makefile but were absent)
- Add header-only utilities table: stream_stats.h, v4l2_fmt.h
README.md:
- Add transport_cli, discovery_cli, config_cli, protocol_cli, query_cli
to CLI tools list
conventions.md:
- Add ERR_NOT_FOUND to Error_Code enum example
- Replace placeholder Invalid_Error_Detail with actual fields
(config_line, message) that have been in use since config module
- Add missing error macros: APP_INVALID_ERROR, APP_INVALID_ERROR_MSG,
APP_NOT_FOUND_ERROR
- Update directory structure: node/ description (was "later"), add web/
and tools/ entries

- 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

Modules (src/modules/):
- common/error: App_Error struct with structured detail union, error codes,
app_error_print(); designed for future upgrade to preprocessor-generated
location codes
- media_ctrl: media device enumeration, topology query (entities/pads/links),
link enable/disable via Media Controller API (/dev/media*)
- v4l2_ctrl: control enumeration (with menu item fetching), get/set via
V4L2 ext controls API, device discovery (/dev/video*)
All modules use -std=c11 -D_GNU_SOURCE, build artifacts go to build/ only.
Kernel-version-dependent constants guarded with #ifdef + #warning.
CLI drivers (dev/cli/):
- media_ctrl_cli: list, info, topology, set-link subcommands
- v4l2_ctrl_cli: list, controls, get, set subcommands
Docs (docs/cli/):
- media_ctrl_cli.md and v4l2_ctrl_cli.md with usage, examples, and
context within the video routing system
