ASLR-dependent ConstEval seeding let E4 miss OOR counterexamples; use a
deterministic seed and force OOR key collisions. Add I9 (NB=12) for the
thermometer fallback path Greptile flagged.

Prove the three pattern detectors work on unseen inputs, not just the RTL
they were derived from. Because detection is functional (ConstEval
fingerprinting over the reachable input space), correctness is established
per case with equiv_opt -assert (full) or a SAT miter clamped to the
reachable range (non-power-of-two), and detection is confirmed with a
w:*tag* probe.
opt_priokey:
D1-D3 spelling variants (explicit shift-or set, compound derived guard,
accumulator also exported) -- all fire and prove equivalent.
E1-E2 parameter sweep P=2..8, S=4..32.
E3 non-power-of-two S=12 reachable-range equivalence via SAT miter.
E4 same shape under -strict declines to rewrite (formal-flow safety).
F1-F2 near-miss negatives (clear accumulator, multi-hot set) -> no rewrite.
opt_prienc (round-robin):
RR4-RR5 DEPTH sweep 8/32, full sequential equivalence.
RR6 non-power-of-two DEPTH=7 reachable-range equivalence (SAT miter).
RR7 an entirely different spelling (upward wrap-scan, first-hit) of the
same arbiter -- fires and proves equivalent.
RR8 fixed-priority (no rotating pointer) negative.
opt_first_fit_alloc (coalesce):
H1 inline same-category compare (no precomputed matrix) spelling.
H2 different slot/field shape (N=8, NB=8, W=3).
All new cases pass locally; they avoid brittle exact cell-count asserts so
they are robust to upstream optimization drift.

Extend two existing opt passes and add one new pass to collapse
serial/dynamic-index structures that were leaving high logic depth:
- opt_first_fit_alloc: recognize the "coalesce-matrix" first-fit
allocator variant (same_cat[i][k] coalescing gated on the leader's
enable, driven from a raw input enable). Rewrite both the lane_slot
allocation and the xbar field gather from one shared log-depth scan.
- opt_prienc: detect round-robin / rotated-priority scans (req scanned
from idx_last downward with wraparound) and rewrite the depth-N
idx--/req[idx] mux chain to rotate -> log-depth priority-encode ->
unrotate.
- opt_priokey (new): recognize priority-by-key one-hot accumulators and
replace each dynamic taken[key] read ($shiftx/$bmux) with the
equivalent pairwise-key-compare reduction, dropping the wide dynamic
indexing. Supports -strict for full-key-range formal validation.
Each includes self-contained tests (equiv_opt / sat -prove-asserts,
mux-bound and negative cases) in tests/opt/.

"Reduce port resize to warning" changed the resize message from
log_warning() to log(), which -q suppresses. Run the resize case without
-q and drop the stale "Warning: " prefix so the message is observed.

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.

- update CMakeLists.txt to load two new files:
- SilimateConfig.cmake: sets Silimate configuration options and defaults
- SilimateVerific.cmake: compiles Verific library, optionally with Silimate modifications
- include silimate tests in test Makefile
