v2.10.0

• Smarter forms, visual routes and a sparkline that fits your data
• ProxyJump chain visualization in detail panel. Shows the full hop route (○ you → ● bastion → ● target) with validation for missing hosts in red
• ProxyJump arrow indicator (→) in host list for hosts using a jump host
• Activity sparkline auto-scales to your data. Ranges from 5 days to 1 year based on connection history
• Sparkline shows dotted baseline (·) for empty periods and a midpoint time label for orientation
• Fewer than 3 connections show a compact text list instead of a sparkline
• Dirty-check on Esc. All four form types now ask "Discard changes?" when you press Esc with unsaved edits
• Auto-submit after picker selection. Pick a key, proxy host or password source and the form submits if ready
• Space bar toggles and cycles. Tunnel type and provider booleans now use Space instead of arrow keys
• Arrow keys are cursor-only in all forms. Left/Right never toggle or cycle values
• HostDetail overlay is no longer a dead end. Press e to edit, T for tunnels, r for snippets
• Signal safety during SSH. Ctrl+C reaches SSH normally but no longer kills purple
• Tunnel processes run in their own process group for clean signal isolation
• Context-aware mode badges in title bar (TAGGING, N SELECTED)
• Search footer shows tag syntax hints (tag: fuzzy, tag= exact) and improved match count (N of M)
• Import confirmation accepts both y and Y
• Consistent footer separators (│) across all screens with shared helper functions
• Help screen updated with Space toggle, detail panel scroll, snippet output navigation and smart-paste hint
• Smart-paste placeholder in Alias field shows user@host:port format
• Edit form title shows the host alias being edited
• 62 new tests covering dirty-check, delete confirmations, navigation, ProxyJump chain resolution and sparkline behavior (3968 total)
