tests: turn.combat.test.js (deterministic RED for BUG-5), deprecate audits

REAL test audit should have been. jest, seeded RNG, mirrors replay-combat.js
op sequence exactly. Asserts per-round invariants: rotation-dupe, turnOrder
dup-id, currentTurn valid+active, HP bounds.

Result: 13 rotation-dupes / 100 rounds. First at round 4 (Cleric twice).
Deterministic, reproducible every run. BUG-5 locked.

Deprecate tests/audit/*.js: random sim gave false 0-violations while
this exact test reproduces bug. Commented early-return. Kept for reference,
delete later when log analyzer + unit tests cover ground.

TODO: BUG-5 added (mid-round addParticipant/revive corrupts rotation).

Root cause hypothesis: computeTurnOrderAfterAddition appends id to
turnOrderIds end. Round wrap re-sorts by initiative. currentTurn pointer
stale after sort → drifts → nextTurn revisits.

Test RED by design (documents live bug). Pre-push will block on push.
