feat: implement universal cache type detection for PSR-16 implementations

- Add universal Redis/Memcached connection detection via reflection
- Support direct cache instance checking (Redis, Memcached, Predis)
- Add recursive property search methods (findRedisInProperties, findMemcachedInProperties)
- Enhance detectCacheType() with multi-level strategy:
  * Level 1: Check already discovered connections (fastest)
  * Level 2: Direct type checking (instanceof)
  * Level 3: Universal reflection for any PSR-16 implementation
  * Level 4: Class name pattern matching (fallback)
- Update getRedisConnection() and getMemcachedConnection() for universal support
- Works with Symfony Cache, direct wrappers, and any custom PSR-16 implementations
- Add phpstan.neon ignore pattern for ReflectionClass generic type warnings

This allows cache type detection to work universally with any PSR-16 cache
implementation, not just Symfony Cache, by recursively searching for Redis/Memcached
connections in object properties.
