- Progress bar: [████████░░░░] 67% 12.3MB/18.5MB
- progressWriter wraps io.Writer, reports bytes via callback
- Footer shows live progress during upload/download
- Auto-refresh destination pane after transfer completes
- Success message shown for 1 second before clearing
- Added dirCache map to sftpPane for caching directory listings
- Cache hit: instant navigation (no disk/network I/O)
- Cache miss: read from disk/SFTP, store in cache per path
- R key clears current directory cache and forces fresh read
- Significant speedup when navigating back to previously visited folders
- Default active pane changed from Remote to Local on SFTP init
- renderPane now takes maxH parameter for fixed border height
- paneStyle.Height(maxH) prevents border from shrinking/growing on scroll
- Stacked mode: maxH = t.height - 6; Side-by-side: t.height - 5
Stacked mode (<50 cols) now shows only the active pane (Local/Remote)
with a visual indicator bar. Tab switches between panes. Side-by-side
mode (>=50 cols) unchanged.
- NEW responsive.go: wrapFooter, adaptiveSidePad, clampWidth, truncateStr
- Footer auto-wraps to multi-line on narrow terminals (full labels preserved)
- Box width clamped to terminal width across all tabs
- Host/key/snippet rows truncated with ellipsis; compact format <35 cols
- SFTP panes stack vertically when terminal < 50 cols
- Tab bar truncates names on overflow
- Form contentW minimum lowered 50->30 for mobile
- Fixed: key_list_tab & snippet_list_tab dropped last data row (off-by-one bug)
