Normalize path input to string, ensure parent directories are created (mkdir with parents=True), and check writability using the normalized path. Replace manual JSON file write with ConfigManager.set("download_path", ...) and add import for ConfigManager. Adjust logging to use logger.error for failures and replace logger.exception where appropriate. These changes improve robustness when saving the download path and centralize config persistence.
When downloading playlists, add --ignore-errors and --no-abort-on-error so a single failure won't stop the entire playlist download. Also normalize values stored in the version cache: coerce version_info to a string (or empty string) and path to a string or None to ensure consistent types when reading/writing cached tool metadata.
Introduce a "generic_mode" option to allow validating/downloading from non-YouTube sites and wire it through the UI, config, and validation logic. Key changes:
- Add generic_mode default to ConfigManager and persist setting from DownloadSettingsDialog (checkbox + help text).
- Extend validate_video_url to accept a generic_mode flag and allow any http/https URL with a domain when enabled; pass this flag from Analysis and Download flows.
- Update YTSageApp to load/save generic_mode, update URL placeholder and settings tooltip behavior, and refresh tooltip when settings change.
- Improve robustness in FormatTableMixin: handle None/incorrect types for format_note, abr, resolution, ext, and codec values to avoid type errors and ensure consistent display.
- Add localization entries for generic mode, placeholder, and related help text across multiple language files and update the in-app default localization strings.
These changes enable broader site support via yt-dlp while hardening UI format handling and keeping user settings persistent.
Renamed 'src/core' to 'ytsage/core' and updated all internal imports to use relative paths. This improves package structure and ensures correct module resolution after the directory move.
