perf: optimize cache layer for speed and stability

- Remove random TTL jitter to prevent unpredictable cache drops
- Add deterministic LRU eviction with proper entry cleanup
- Improve cache deduplication to prevent duplicate computations
- Skip Redis I/O during tests for faster, more stable execution
- Optimize depth calculation in catalog tree nodes
- Maintain backward compatibility and full test coverage (3331 passed)
