Add serial/protocol modules to plan, binary format to arch, -flto to Makefiles

Browse Source 
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.

| # | Module | Status | Notes |
|---|---|---|---|
| 1 | `common` | not started | Error types, base definitions — no dependencies |
| 2 | `media_ctrl` | not started | Media Controller API — device and topology enumeration, pad format config |
| 3 | `v4l2_ctrl` | not started | V4L2 controls — enumerate, get, set camera parameters |
| 4 | `transport` | not started | Encapsulated transport — header encode/decode, framed TCP read/write |
| 5 | `frame_alloc` | not started | Per-frame allocation with bookkeeping (byte budget, ref counting) |
| 6 | `relay` | not started | Input dispatch to output queues (low-latency and completeness modes) |
| 7 | `ingest` | not started | MJPEG frame parser (two-pass EOI state machine, opaque stream → discrete frames) |
