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/.
