Introduces EPG data fetching and program selection in main.py, allowing users to choose a program from the EPG guide if the start date is within the last 7 days. Adds get_epg_data_at and select_program_from_epg utilities to input.py, and updates stream_selection to include channel info in the returned selections.
Improved code structure and docstrings in utils/input.py, updated imports for clarity, and enhanced validation error handling. Added pylint to the dev dependency group in pyproject.toml for code quality checks. Removed unused imports from main.py.
