URL Processing:

Added URL pre-filtering to avoid unnecessary yt-dlp checks
Added common video platform patterns for quick filtering
Reduced error logging noise from non-URL words
Improved URL validation efficiency
FFmpeg Management:

Enhanced FFmpeg binary verification
Added robust error handling for subprocess calls
Improved cleanup of failed operations
Added detailed logging for binary operations
Error Handling:

Fixed exception hierarchy in utils/exceptions.py
Added proper error types for different failure scenarios
Enhanced error messages with more context
Improved error propagation through the system
Process Flow:

Added proper timeout handling for subprocess calls
Enhanced environment variable handling
Better cleanup after failures
Added retry mechanisms for failed operations
