Exception Hierarchy:

Added missing exceptions to utils/exceptions.py:
ResourceExhaustedError
ProcessingError
CleanupError
FileOperationError
Fixed exception imports in exceptions.py
Added proper re-exports of all exceptions
Maintained backward compatibility aliases
URL Processing:

Added pre-filtering for URLs before yt-dlp checks
Added common video platform patterns
Reduced error logging noise
Improved URL validation efficiency
Error Handling:

Added proper error types for all operations
Enhanced error messages with context
Added resource exhaustion checks
Improved error propagation
Code Organization:

Centralized exceptions in utils/exceptions.py
Proper re-exports in exceptions.py
Consistent error handling across components
Better error type hierarchy
