feat(codec): extend BraidDiatCodec with BraidDiatFrame encoder/decoder
- BraidDiatCodec.lean: BraidDiatFrame now handles encode/decode of full SpherionState × BraidReceipt with 256-bit header and variable mountain list - braid_diat_codec.py: Python extraction updated to match, benchmark artifact at shared-data/artifacts/braid_diat_codec_benchmark.json (714B avg vs messagepack 1748B avg) Build: lake build Compiler 3313 jobs, 0 errors
