Describe the Bug

When enabling the Astro Language Support extension in Visual Studio Code, the Astro VS Code helper process consistently uses around 110% CPU on my Apple Silicon (M2 Max) MacBook Pro.

This happens even when I’m not working in an Astro project, which leads to significant battery drain. Disabling the extension immediately stops the high CPU usage.

Environment:

• macOS (Apple Silicon M2 Max)
• VS Code version: 1.10.5
• Astro Language Support version: 2.15.4

Steps to Reproduce

1. Enable the Astro Language Support extension in VS Code.
2. Open any non-Astro project.
3. Observe CPU usage in Activity Monitor — the “Astro VS Code helper” process stays around 100–110%.
