v2026.06.16-alpha

• bugfix Fixed local terminal tab close causing entire app to crash. Root cause: multiple goroutines concurrently calling ConPTY.Close() → double ClosePseudoConsole on Windows triggers OS-level access violation unrecoverable by Go's recover(). Fix: wrap entire Disconnect() body in sync.Once.
• bugfix Fixed terminal output loss when switching tabs. Data arriving during KeepAlive deactivation was buffered in sessionStore but never replayed on reactivation. Track written chunk count and replay missed chunks in onActivated.
• bugfix Fixed Enter key not triggering reconnect after SSH disconnect occurred while tab was in background. session:status event was dropped by isActive guard, so retryOnEnter never got set. Sync from sessionStore.getStatus() on reactivation.
• bugfix Fixed suggestion popup stuck at top-left after SSH reconnect. terminalInput held stale reference to disposed terminal, cursor tracking returned {0,0}. Recreate terminalInput when session ID changes.
• bugfix Fixed terminal content being cleared after reconnect. Release + acquire created a new xterm.js instance. Use transferTerminal() to move the existing terminal entry to the new session ID, preserving scrollback.
• bugfix Fixed pressing Ctrl+G / Shift+G / PageDown in vim leaving rendering residue. \x1b[2J replacement with scrollClear was also applied in alternate screen buffer, corrupting vim's screen state. Now only applies to main buffer.
• bugfix Fixed sidebar resize handle blocking the connection list scrollbar. Moved activation area outside the sidebar edge via negative right offset.
• improve Text highlighting overhaul:
  • Highlight only resets foreground color (\x1b[39m) instead of all SGR (\x1b[0m), preserving vim's reverse video selection
  • Lines with display attributes (reverse video, bold, etc.) skip highlighting to avoid color mixup
  • File path regex now matches directories and files without extensions, anchored by (^|\s) to avoid false positives inside words
  • Added datetime formats: HH:MM without seconds, ISO 8601 Z suffix, syslog Mon DD HH:MM:SS, weekday+year Wed Jan 21 HH:MM:SS YYYY
  • Color palette extracted into named constants; number color 145→152, brace color 147→223 for better contrast on vim reverse video
  • Local terminal sessions no longer apply text highlighting
  • Suggestion popup no longer triggers on arrow key navigation when closed
• refactor Merged WorkspaceTabItem into TabItem, eliminating ~300 lines of duplicate code. All tab types (terminal, workspace, SFTP, RDP, VNC, etc.) handled by a single component.
• improve Tab close buttons replaced plain × text with Lucide X SVG icon, adjusted sizing and spacing to prevent text shift when switching tabs. AI lock button always visible. SFTP and Monitor context menu items hidden for local terminal panels.
• bugfix Fixed AI lock state being cleared when panel detached from workspace tab.
