f448b61f5e* fix: defer plugin entrypoint loading until runtime Fixes simonw/sqlite-utils#713 * Lazy-load plugins when listing them Keep plugin entrypoints from loading at module import time, but preserve the existing behavior of get_plugins() by loading entrypoints the first time plugins are listed outside tests. --------- Co-authored-by: Simon Willison <swillison@gmail.com>
