feat: wire BraidDiatCodec into FAMM transport

Browse source 
BraidDiatCodec (714 bytes avg) imported alongside VCN encoder.
When available, can replace Delta+RLE for braid data encoding.

Benchmark (from braid_diat_codec_benchmark.json):
  BraidDiat: 0.029ms encode, 0.034ms decode, 714 bytes
  MessagePack: 0.103ms encode, 0.002ms decode, 1748 bytes
  Cap'n Proto: 0.002ms encode, 0.0001ms decode, 29 bytes

BraidDiatCodec is 2.5x smaller than MessagePack and encodes
braid data natively (Q0_2 fields, Mountain packed, MMR state).
