- Reset cursor to '..' (position 0) when entering an archive so it
doesn't stay at the previous directory's cursor position
- Fix archive exit landing in /tmp when pressing Enter on '..' inside
an archive by delegating to archive-aware goParent() in enterSelected()
- Fix goParent() to handle ALL navigation within archive mounts
explicitly instead of falling through to filepath.Dir which may
navigate outside the mount to /tmp
- Fix format cycling text color reset by preserving '(f to change)'
hint in modal note, ensuring renderModalNoteLine applies proper
key/action styling via the '(' separator match
Replace full ANSI reset sequences (\x1b[0m) added by lipgloss.Render() for
gutter markers, cursor highlights, and selection highlights with
background-preserving resets (\x1b[39;22;23;24;59;48;2;R;G;Bm) that restore
the panel background color.
Without this fix, every \x1b[0m from lipgloss-styled elements in
renderTextCursorContent resets the panel background (set by the outer
renderPreviewContent wrapper), causing some letters to have incorrect or
missing background color in caret mode.
