test: round 100 — findFiles maxAge+recursive interaction, parseSessionMetadata ### truncation, cleanupAliases falsy coercion

- findFiles with both maxAge AND recursive combined (option interaction test)
- parseSessionMetadata truncates item text at embedded ### due to lazy regex
- cleanupAliases callback returning 0 (falsy non-boolean) removes alias via !0 coercion

Total tests: 860
