Add missing modules (config, discovery, reconciler, ingest) and update
node description from "later" to reflect its current done state.

- protocol.md: add START_DISPLAY (0x000A) and STOP_DISPLAY (0x000B) wire
schemas and field descriptions; add both to command table
- xorg.md: add 'Multiple windows' section covering glfwPollEvents global
behaviour, per-context glfwMakeContextCurrent requirement, and
glfwInit/glfwTerminate ref-counting; includes the gotcha that
short-circuiting the event loop can starve non-polled windows
- planning.md: add cooperative capture release deferred decision;
add xorg viewer remote controls (zoom, pan, scale, future shader
post-processing) to deferred decisions; note xorg viewer controls
not yet exposed remotely in module table

Connects to a running video node by host:port. Supports:
enum-devices, enum-controls, get-control, set-control,
start-ingest, stop-ingest
Uses semaphore-based request/response synchronisation (same pattern as
query_cli). start-ingest maps directly to the new START_INGEST protocol
command with optional format/size/fps args; defaults to auto-select.

reconciler: generic resource state machine — BFS pathfinding from current
to wanted state, dependency constraints, event/periodic tick model.
reconciler_cli exercises it with simulated device/transport/stream resources.
ingest: V4L2 capture module — open device, negotiate MJPEG format, MMAP
buffer pool, capture thread with on_frame callback. start/stop lifecycle
designed for reconciler management. Transport-agnostic: caller wires
on_frame to proto_write_video_frame.

Document the wanted/current state separation, generic resource state
machine reconciler (BFS pathfinding, event + periodic tick), node state
queries (GET_CONFIG_STATE / GET_RUNTIME_STATE), stream ID assignment
by controller, and connection direction model.
Add reconciler module to module order and reconciler_cli experiment
to CLI tools table in planning.md.

Add stream_send_cli (V4L2 capture → TCP → VIDEO_FRAME) and
stream_recv_cli (TCP → threaded frame slot → GLFW display) to
exercise end-to-end streaming between two nodes on the same machine
or across the network.
Add include/stream_stats.h (header-only rolling-window fps/Mbps tracker)
and include/v4l2_fmt.h (header-only V4L2 format enumeration shared between
v4l2_view_cli and stream_send_cli). Refactor v4l2_view_cli to use the
shared header.

- tools/gen_font_atlas: Python/Pillow build tool — skyline packs DejaVu
Sans glyphs 32-255 into a grayscale atlas, emits build/gen/font_atlas.h
with pixel data and Font_Glyph[256] metrics table
- xorg: bitmap font atlas text overlay rendering (GL_R8 atlas texture,
alpha-blended glyph quads, dark background rect per overlay)
- xorg: add xorg_viewer_set_overlay_text / clear_overlays API
- xorg: add xorg_viewer_handle_events for streaming use (events only,
no redundant render)
- xorg_cli: show today's date as white text overlay
- v4l2_view_cli: new tool — V4L2 capture with format auto-selection
(highest FPS then largest resolution), MJPEG/YUYV, measured FPS overlay
- docs: update README, planning, architecture to reflect current status

README status table was showing transport/discovery/protocol/node as
"not started" when all are done. Added summary sentence, notes column,
config and dev/web rows. Fixed dev/web structure description.
planning.md: removed stale "prerequisite" note about web UI — it is
already implemented and working.

- 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

Config_Def schema tables declare section/key/type/default per module.
Typed getters: config_get_str, _u16, _u32, _flags.
FLAGS type parses space/comma-separated tokens via a Config_Flag_Def table.
config_defaults() gives schema defaults without a file.
config_dump() prints effective values for diagnostics.
config_cli: load a file or --defaults and dump effective config.
dev/example.cfg: sample config covering node, discovery, transport.

Sends 6-byte framed announcements to 224.0.0.251:5353 on startup and
every interval_ms (default 5s). Receive thread maintains a peer table
(max 64 entries); fires on_peer_found for new peers, on_peer_lost when
a peer misses timeout_intervals (default 3) consecutive intervals.
Own announcements are filtered by name+site_id. SO_REUSEADDR+REUSEPORT
allows multiple processes on the same host for testing.
discovery_cli: announce <name> <tcp_port> [flags] — prints found/lost events.
Also notes future config module in planning.md.

ingest module: dequeue V4L2 buffers, emit one encapsulated frame per buffer.
Driver guarantees per-buffer framing for V4L2_PIX_FMT_MJPEG; no scanning needed.
mjpeg_scan: future optional module for non-compliant hardware only.
Explicitly a workaround, not part of the primary pipeline.

xorg module: XRandR geometry queries, screen grab source (XShmGetImage),
frame viewer sink (XShmPutImage, fullscreen per monitor). All exposed as
standard source/sink node roles on the existing transport.
Audio: deferred but transport is already compatible — channel_id mux,
audio_frame message type slot reserved, relay/allocator are payload-agnostic.
Also marks serial as done in planning.md.

- dev/web/ is the browser-side equivalent of dev/cli/ — a Node.js dev UI
that speaks the binary protocol and exposes V4L2/topology inspection
- Explicitly noted as blocked on transport+protocol being finalised
- Distinguished from the future production dashboard
- Directory structure updated to show serial/transport/protocol modules

architecture.md:
- Web interface connects as a first-class binary protocol peer; no JSON
bridge in C; DataView in JS maps directly to get_u32 etc.
- Future preprocessor section: protocol schema defined once, emits both
C (put/get, write_*/read_*) and ESM JS (DataView encode/decode);
same tool as planned for error location codes
planning.md:
- Add web node (entry #11) to module order
- Add Future: Protocol Preprocessor section above Deferred Decisions
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
architecture.md: replace JSON control payloads with binary serialization;
add Protocol Serialization section describing little-endian wire format,
put/get buffer layer, and write_*/read_* protocol layer.
planning.md: mark common/media_ctrl/v4l2_ctrl done; insert serial (#4)
and protocol (#6) modules with descriptions.
conventions.md: document -flto and its implication (no manual static for
inlining — compiler handles it at link time).
Makefiles: add -flto to CFLAGS in all four Makefiles.

Move modules under src/modules/ and public headers under include/,
keeping dev/, tests/, and docs at the top level. Adds a placeholder
for src/node/ where the final video node entry point will live.

Initial documentation for the multi-peer video routing system:
- architecture.md covers graph model, transport protocol, relay design,
and the Pi get-it-on-the-wire-first rationale
- planning.md defines module build order and directory structure
- conventions.md captures C11 code style, naming, error handling approach,
and directory layout rules
