feat(cache): add FileCache implementation for file-based caching

- Introduce FileCache class implementing PSR-16 CacheInterface
- Store cache items as serialized files with expiration timestamps
- Support single and multiple get, set, delete operations
- Automatically create cache directory if it does not exist
- Handle cache expiration and invalid data by deleting stale files
- Use hashed keys to generate cache file names in a dedicated folder
