When a viewer window has no incoming stream, renders animated analog-TV
noise (hash-based, scanlines, phosphor tint) at configurable fps (default
15) with a centred "NO SIGNAL" text overlay.
- xorg: FRAG_NOSIGNAL_SRC shader + xorg_viewer_render_no_signal(v, time, noise_res)
- main: Display_Slot gains no_signal_fps + last_no_signal_t; display_loop_tick
drives no-signal render on idle slots via clock_gettime rate limiting
- protocol: START_DISPLAY extended by 2 bytes — no_signal_fps (0=default 15)
+ reserved; reader is backward-compatible (defaults 0 if length < 18)
- controller_cli: no_signal_fps optional arg on start-display
- docs: protocol.md updated with new field

- 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

START_INGEST carries stream_id, format/width/height/fps, dest_host:port,
transport_mode (encapsulated or opaque), and device_path. All format fields
default to 0 (auto-select). STOP_INGEST carries stream_id only.
Both commands set wanted state on the node; reconciliation is asynchronous.
Protocol doc updated with wire schemas for both commands.

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.

Both sites default to site_id=0; gateway must rewrite site_id in
announcements and protocol messages crossing the boundary. site_id=0
on a cross-site link is a gateway protocol error.

Covers all layers: TCP → transport frame → message type dispatcher →
payload schemas. Documents frame format (6-byte header), all message
types, STREAM_OPEN/CLOSE lifecycle, codec/pixel_format/origin tables,
stream events, and discovery announcement wire format.
Also fixes stale channel_id reference in audio section of architecture.md.
