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.

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.
