Enhance HLS proxy functionality and improve caching mechanism

Browse Source 
- 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.

- app.py - main Flask application file that handles incoming HTTP requests and interacts with yt-dlp through functions from dlp.py.
- dlp.py - module for interacting with yt-dlp, containing functions to get HLS playlists and segments.
- dlp.py - module for interacting with yt-dlp, containing functions to get HLS playlists and segments. examine yt_dlp/YoutubeDL.py in venv in order to understand how to use yt-dlp for getting HLS playlists and segments
functions:
- get_hls_playlist(video_url): gets HLS playlist for the specified video as a string that can be returned to the client. The segment list should be filtered to only include those available for the given video and supported by yt-dlp.
- get_hls_segment(video_url, segment_name): gets the specified video segment: downloads it using yt-dlp and returns its content as bytes that can be returned to the client. It should also use yt-dlp to download the segment since only yt-dlp can handle the necessary authentication and access control for the video content.
it should also rewrite segment filenames in case if they expire during of before download, so that they can be requested through the proxy using predictable URL structure.
- get_hls_segment(video_url, segment_filename): gets the specified video segment for rewritten filename: downloads it using yt-dlp and returns its content as bytes that can be returned to the client. It should also use yt-dlp to download the segment since only yt-dlp can handle the necessary authentication and access control for the video content.
caching:
- Caching of yt-dlp sessions will be implemented using a simple in-memory dictionary that will store video parsing results for each VIDEO_ID. No complex in-memory solutions, just a dictionary with TTL for each key. TTL will be set to 365 days, which will effectively cache results and minimize repeated requests to yt-dlp.
