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.

site_id (u16) is reserved in the announcement payload from day one,
always 0 in single-site deployments. Documents the site gateway node
concept and fully-qualified addressing (site_id:namespace:instance) so
multi-site can be added later without wire format changes.

A node can declare multiple roles simultaneously (e.g. relay + sink).
Replaces the function string with a fixed-size flags field; keeps the
payload layout simple and fixed-width up to the name.

Reuse UDP multicast transport (224.0.0.251:5353) with our own binary
wire format — no Avahi, no Bonjour, no daemon dependency.

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

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.

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
