Description
### Extension Version
0.20260612.1
### VS Code Version
1.124.2
### Operating system Version
Windows 11 Pro 25H2 26200.8655
### Steps to reproduce
1. Open a .ts file in VS code
2. Select "TypeScript Native Preview: Enable (Experimental)" in the command palette
3. Select "Use TypeScript Native Preview (Experimental) 0.20260612.1" in the TS version selector
### Issue
Nothing happens, VS Code keeps using TypeScript version that was used before, either from workspace or bundled.
I have the following line in the "typescript-native-preview" output channel:
```
2026-06-12 17:08:48.505 [info] TypeScript Native Preview is disabled. Select 'Enable TypeScript Native Preview (Experimental)' in the command palette to enable it.
```
I've tried restarting extension host, restarting VS Code, reinstalling the extenstion, nothing helps.
