typed-decay.test.ts (TV6 typed memory decay, 15 asserts) sat in
tests/unit/memory/ which no runner glob collected -> orphan (never ran).
Adds 'memory' to the subdir brace-glob in all runner sources (package.json
scripts + ci.yml shards) and the COLLECTORS mirror in check-test-discovery.mjs
(drift-check keeps them in sync). Passes standalone (15/15); DATA_DIR isolation
handled per-file by tests/_setup/isolateDataDir.ts.
