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.

+### BUG-5: mid-round addParticipant/revive corrupts rotation (deterministic test)
+- Test: `shared/tests/turn.combat.test.js` (jest, seeded RNG, RED).
+- 13 rotation-dupes / 100 rounds. First at round 4 (Cleric twice).
+- Pattern: Reinforce/Summon added mid-round → appears in rotation same round
+  → round wrap re-sorts by initiative → currentTurnParticipantId pointer
+  stale → nextTurn revisits.
+- Root cause: `computeTurnOrderAfterAddition` appends id to turnOrderIds
+  end + `togglePause` resume rebuilds order via sort but doesn't re-anchor
+  currentTurn to its new position. After several mid-round adds the pointer
+  drifts.
+- This is the test audit should have been. Mirrors replay-combat.js op
+  sequence exactly (damage, heal, conditions, toggleActive, deathSave,
+  remove, add, edit, pause/resume, reorder, revive-between-rounds).

 ## Pipeline
 - [ ] Red test: dead participant still in turnOrderIds, turn still advances to them
 - [ ] Fix `shared/turn.js`: don't drop dead from turn order
