To use the Tabby VSCode extension in a local workspace instead of a devcontainer, you can follow these steps:

1. Install the Tabby VSCode extension in your local VSCode environment.
2. Configure the Tabby extension to use the local workspace directory for data storage.
3. Ensure that the Tabby extension is pointing to the correct data directory in your local workspace.
4. Verify the Tabby extension settings to confirm that it is set up for local workspace usage.
5. Test the Tabby extension functionality in the local workspace to ensure it works as expected without relying on the devcontainer setup.
