This handles DuckDB extension installation and updates through a clean command line interface. You can install from core or community repos with the name@repo syntax, or pass --update to refresh everything at once. It checks if DuckDB is installed first and gives you platform specific install commands if not. The update mode is thorough: it checks the CLI version against the latest stable release and prompts you to upgrade before updating extensions. Nice touch that it batches all the SQL statements into a single DuckDB call instead of spawning processes for each extension. Saves you from writing the same boilerplate SQL every time you need to add spatial or parquet support to a project.
