fix: header size mismatch — host sent 16 bytes, client read 13

dami etoile committed Jun 234250baa

The keyframe byte was packed as a 4-byte array to satisfy concat(),
making the header 16 bytes. Client expected 13 bytes (12 + 1 kf flag),
causing every frame's header parse to be misaligned by 3 bytes.

Now: header is 12 bytes (w+h+size) sent via concat, then 1 byte kf flag
sent separately. Total = 13 bytes, matching client.
