V0.2.2

Added

Multi-Tab Terminal Support

• Multiple terminal tabs - Open up to 10 concurrent terminal sessions, similar to gnome-terminal or iTerm2
• Independent sessions - Each tab maintains its own:
  • Shell selection (Bash, Zsh, Sh)
  • SSH key configuration
  • WebSocket connection and PTY session
  • Command history and state
• Tab management features:
  • Click + button to add new terminal tab
  • Click x on tab to close (minimum 1 tab required)
  • Double-click tab title to rename
  • Click tab to switch between terminals
• Visual status indicators - Green/red dot on each tab shows connection status
• Session persistence - Tab configurations (title, shell, SSH key) saved to localStorage and restored on page reload
• Status bar - Shows current tab count, active shell, and SSH key info

Changed

Frontend Architecture

• Refactored Terminal.jsx into modular components:
  • TerminalContext.jsx - React Context + useReducer for tab state management
  • TabBar.jsx - Tab navigation with Material-UI Tabs component
  • TerminalPane.jsx - Individual xterm.js terminal instance per tab
• Improved terminal lifecycle management - sessions persist when switching tabs

Build Optimization

• Code splitting with Rollup manual chunks to eliminate 500KB bundle warning:
  • vendor-react - React, React DOM, React Router (~160KB)
  • vendor-mui - Material-UI components and icons (~298KB)
  • vendor-xterm - xterm.js terminal emulator (~334KB)
  • index - Application code (~104KB)
• Parallel chunk loading for faster initial page load

Fixed

• Fixed terminal session being destroyed when switching between tabs
• Fixed duplicate tabs appearing on fresh start (localStorage race condition)
• Fixed corrupted terminal display when tab initialized while hidden

New Files

• frontend/src/context/TerminalContext.jsx - Tab state management with React Context
• frontend/src/components/TabBar.jsx - Tab navigation component
• frontend/src/components/TerminalPane.jsx - Individual terminal instance component
