Proxy URIs may contain embedded userinfo (username/password). Add a small sanitizer helper and use it for proxy mapping and proxy selection logs to avoid leaking credentials.
- Add configurable title caching with fallback support
- Cache titles for 30 minutes by default, with 24-hour fallback on API failures
- Add --no-cache and --reset-cache CLI flags for cache control
- Implement region-aware caching to handle geo-restricted content
- Use SHA256 hashing for cache keys to handle complex title IDs
- Add cache configuration variables to config system
- Document new caching options in example config
This caching system significantly reduces redundant API calls when debugging
or modifying CLI parameters, improving both performance and reliability.
