maude: Phase 5 system modules + rewrite rules (21 tests, 159 total)

lib/maude/rewrite.sx: rl/crl transitions interleaved with eq normalisation.
mau/rewrite = default strategy (top-down, leftmost-outermost, first rule);
mau/rew bounded; mau/search = BFS reachability over all successors.

lib/maude/fire.sx: short-circuiting matcher (mau/fire-eq) — finds the first
productive match instead of enumerating the whole solution set. Fixes the
exponential blowup of AC rewriting on many identical elements (8 coins:
60s+ to <1s). Eager match-multiset kept only for match-all / search.

Verified on AC coin-change, traffic light, branching search, crl clock.
