mikael-lovqvists-claude-agent ff48559b12 Add transport module: TCP framing, thread-per-connection, inbound limit
transport_server_create/start: binds TCP, spawns accept thread, closes
excess inbound connections when max_connections is reached.

transport_connect: outbound TCP, spawns read thread before returning.

transport_send_frame: packs 8-byte header with serial put_*, then writes
header + payload under a per-connection mutex (thread-safe).

Read thread: reads header, validates payload_length <= max_payload, mallocs
payload, calls on_frame (callback owns and must free payload). On error or
disconnect calls on_disconnect then frees conn.

transport_cli: server mode echoes received frames; client mode sends 3
test frames and prints echoes.

video-setup

A graph-based multi-peer video routing system written in C11. Nodes are media processes connected by typed transport edges; the graph carries video streams between sources, relays, and sinks with priority as a first-class property — so a low-latency monitoring feed and a high-quality archival feed can coexist on the same source.

Designed to run on resource-constrained hardware (Raspberry Pi capturing raw MJPEG, forwarding over TCP) alongside more capable machines that handle processing, relay, display, and archival.
