js-rigor: batch cache staleness, tx-batch crash, TTL bypass; value freshness campaigns

Engine fixes:
- RelationUpdates.updateRelationsBatch: invalidate arbiter-level caches
  (rule result cache, ChainRule caches, direct-check cache) per affected
  relation — batch updates bypassed Arbiter.addRelation and served stale
  decisions after batch modify/swap with warm caches
- updateRelationsBatchTransactional rollback: new Map(Set) crashed with
  'Iterator value is not an entry object' — fixed to new Set
- RelationalComparatorRule: value extraction (direct-list and cached
  direct paths) now gates on valueManager._isValueExpired — TTL-expired
  values no longer feed comparator decisions

Campaigns:
- value-freshness-parity.test.js: batch modify/swap/tx rollback freshness
  with comparator mirror (batch MODIFY of a missing relation is a silent
  no-op — pinned)
- ttl-expiry-parity.test.js: injected-clock TTL expiry through the
  comparator path (exact parity with caching off; bounded staleness with
  caching on), faithful changed_last_at mirror semantics

/**
* rigor/ttl-expiry-parity.test.js — value-TTL expiry through the full
* comparator check path with an injected clock.
*
* Contracts pinned:
* - values written with setTTL(rel, ttlMs) expire after ttlMs of engine
* time; expired operands no longer participate in relational
* comparisons (the comparator's value extraction must consult the
* value manager's TTL gate, not raw relation values).
* - with the decision cache enabled, a decision cached before expiry may
* linger up to the rule-result-cache TTL, but MUST become fresh once
* the cache entry itself expires (bounded staleness).
*
* The mirror tracks per-relation write timestamps under the same injected
* clock and computes the expected comparison result.
