feat: implement intelligent terminal routing for Python and Node.js commands

- Python commands (python, pip, conda, venv, py) now automatically route to backend terminal
- Node.js commands (npm, yarn, pnpm, node, npx, vite, next, react, webpack) route to frontend terminal
- Commands execute in appropriate working directories with auto-creation of backend/frontend folders
- Fixed Console component typo and updated PreviewPanel to show all terminals in System Messages section
- Priority: Python > Node.js > existing chat mode logic
