Add `bitpack_compare_sweep`, which exercises the public `array.binary(rhs, op)` compare-against-constant path over all eight integer types and every valid bit width (64Ki in-range elements per case, no patches). It isolates the `<BitPacked as CompareKernel>` unpack + per-element compare kernel so a kernel change shows up as a CodSpeed diff. Signed-off-by: Joe Isaacs <joe.isaacs@live.co.uk>

Summary
Adds
bitpack_compare_sweep, a benchmark exercising the publicarray.binary(rhs, op)compare-against-constant path over all eight integer types and every valid bit width (64Ki in-range elements per case, no patches, no out-of-range fast path). It isolates the<BitPacked as CompareKernel>unpack + per-element compare kernel.This is the base of a stack: it lands the benchmark measuring the current streaming kernel so that the follow-up kernel change (fused
unpack_cmpmask + untranspose) shows up as a CodSpeed diff against this branch.Checks
