Module blake3 

BLAKE3 circuit gadgets.

This module provides circuit primitives for the BLAKE3 hash function. The primitives are exposed as free functions that take input wires and return output wires — no wrapping structs.

The entry points are:

• blake3_compress — single-block compression primitive, its rounds split across the two 32-bit lanes.
• blake3_compress_2x_seq — two sequential compressions sharing one parallel core.
• blake3_chunk — single-chunk (up to 16 blocks) chaining-value gadget.
• blake3_fixed — full hash gadget for messages of compile-time-known length, spanning any number of chunks via BLAKE3’s parent tree.
• blake3_keyed_fixed — the same gadget in BLAKE3’s keyed mode.
• blake3_keyed_fixed_2x — two keyed hashes of equal-length messages, run side by side.
