feat(Sky): Add VS Code terminal and language detection node_modules

Add @xterm/xterm with all addon packages and @vscode/vscode-languagedetection to dependencies. Update the astro.config.ts build step to copy these node_modules to Static/Application/node_modules/ for runtime access.

These packages are required for VS Code's terminal emulation and language detection functionality, enabling the editor to provide full VS Code feature parity.
