Bitwise and shift test vectors.
Shift/rotate input: u64 value (8 bytes) + u32 shift amount (4 bytes). Binary ops input: two u64 values (16 bytes). Unary ops input: one u64 value (8 bytes). Output: one u64 result (8 bytes).
Each operation comes with a baked-corpus _suite() -> u64 that
XOR-folds the per-case u64 results into a single fingerprint —
consumed by the three-way conformance harness.
