Install the VS Code extension

1. Install xlflow and the Excel bridge using Installation.
2. Enable Trust access to the VBA project object model in Excel.
3. Install the xlflow extension from the VS Code Extensions view or the packaged release.
4. Open a folder containing xlflow.toml.
5. Run xlflow: Check Environment or xlflow doctor --json.

If the CLI is not on PATH, set:

{ "xlflow.path": "C:\\Users\\me\\AppData\\Local\\xlflow\\xlflow.exe" }

Reload VS Code after changing the path. The extension is Windows-only because workbook-backed operations use Excel COM.
