package.json repository URL points to miden-lsp instead of vscode-extension

The VS Code extension package metadata currently points its `repository.url` at:

```json
"https://github.com/0xpolygonmiden/miden-lsp"
```

but this package lives in `0xMiden/vscode-extension`.

That can send users, marketplace tooling, or package metadata consumers to the language server repository when they are looking for the extension source. A small metadata fix should update the repository URL to this repository.

Find the package.json file in the repository root. Update the repository.url field from 'https://github.com/0xpolygonmiden/miden-lsp' to 'https://github.com/0xMiden/vscode-extension'. Verify the change by checking the file structure and ensuring no other references need updating. Run any existing validation or build scripts to confirm the metadata is correct.
