23b021a26b Fix opt_compact_prefix wide packs and opt_priority_onehot max-width test 
The tests/silimate suite (which aborted the Run tests CI job) exposed two
issues in the generalized passes:

- opt_compact_prefix: the forward dense pack regressions at 64 and 128 bits
  no longer rewrote. The ConstEval fingerprint was uint64_t-based (capped at
  62 bits) and the per-cone cell cap (max_width*96) was below the O(width^2)
  cell count of a wide pack. The fingerprint now drives whole-width Const
  bit patterns (no width cap) and the cone cap scales quadratically; total
  work stays bounded by the shared walk/eval budgets.

- opt_priority_onehot: the "max-width below lane count" negative test set
  max_width=8 on a 16-lane design expecting no rewrite, but the generalized
  matcher legitimately (and equivalence-provably) rewrites the 8-lane
  sub-region. The test now uses max_width=3 (below min_width 4) to verify
  the width gate suppresses all matching.
