For self-hosted knots, clone URLs may differ based on your setup.
sweep input sizes from 4 B to 1 MiB with deterministic pseudo-random
data, exposed via `deno task bench`.
the byte-at-a-time loop carried a per-iteration crc dependency that
the JIT could not pipeline. with 7 additional precomputed tables, each
8-byte window resolves through 8 independent lookups XOR-reduced
together, roughly doubling throughput on inputs ≥ 64 bytes. the byte
loop is retained for the 0..7 byte tail.
CRC-32/ISO-HDLC checksum — the variant used by zip, gzip, PNG, RAR, and most archive formats.
