✨ Bug Fixes
- Downloads: fixed an issue where selecting “download subtitles” alongside video downloads caused the progress not to display.
- Subtitles: fixed incorrect CPS/WPM/CPL calculations.
- Proxy: fixed an issue where not passing the `timeout` parameter made the UI show “saved successfully” even though the backend change didn’t apply.
- Downloads (Windows): fixed garbled text in task details when filenames contained Chinese characters.
- Dialogs (Windows): fixed a prompt saying “shellitem is nil” when a dialog was closed for reasons other than “OK”.
