/**
 * applyCachePolicy — internal helper for injection factories.
 *
 * Each factory (`defineSkill`, `defineSteering`, `defineFact`,
 * `defineInstruction`, `defineMemory`) calls this to merge the
 * consumer-supplied `cache` option with the flavor-specific default.
 * The merged policy lands in `Injection.metadata.cache` for the
 * CacheDecision subflow (Phase 4) to read back.
 *
 * Why it lives in src/cache/ (not co-located with each factory):
 *   - Single source of truth for per-flavor defaults
 *   - Tests for the defaults live in one place (test/cache/)
 *   - Adding a new factory means adding one entry to the map below;
 *     not duplicating the default-resolution logic five times
