Enhance HLS proxy functionality and improve caching mechanism

- Updated AGENTS.md to clarify dlp.py module usage and segment handling.
- Modified README.md to include ALLOW_LOCAL configuration for testing.
- Refactored app.py to streamline HLS proxy logic and improve error handling.
- Enhanced dlp.py to optimize caching and segment retrieval processes.
- Updated player.html to ensure proper JSON formatting for proxy URLs.
- Improved test_integration.py to validate HLS segment proxying and added test for Pornhub HLS extraction.
- Adjusted test_proxy.py to reflect changes in caching functions and data structure.
