The max_pairs budget was a single running counter shared across all
req_wire iterations, so once a start-candidate-heavy first req size
exhausted it, every later req size broke on its first start candidate and
was silently skipped. Reset the budget per req_wire so all req sizes get
a fair chance. (Completeness only; fingerprint_rr still validates every
match, so this never affected correctness.)

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/.

- pack_lanes: assert elem_w < 32 and pack the full element width instead
of silently dropping bits >= 31.
- Remove the dead `cell` struct member and its unused assignment in run()
(every emit helper shadows it with its own local `cell`).
- Decorrelate the pseudo-random bc bits from en (independent mix) so they
no longer share an LFSR bit (e.g. en[7]/bc[0] for n=8).
- Add purpose comments to fingerprint_dsel and lane_of_bit.
Declined the std::stoi/std::stoll arg-parsing suggestion: it matches the
established convention in sibling passes (opt_argmax, opt_priority_onehot).

- 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
Rewrite power-of-two indexed word selects to $bmux when the shift
amount already carries the scale as low zero bits.
Keep the rule to non-overlapping selections and bound the generated
mux ways. Add regressions for aligned shifts, padding, signed
extension, and shiftmul handoff cases.
