fix: filebrowser scroll+lang hover+black-flash+shell one-line

- filebrowser: select() only scrollIntoView on keyboard, not hover
- lang-switch: .lang-switch:hover → invert rule (header excluded before)
- black-flash: color-scheme light; dark script sets colorScheme
- shell: flex-wrap nowrap; keepEnd() scrolls on input
