• I’d consider extracting the “scan app plugins, supporting flat + vendor/plugin layout” logic into a small shared helper, because the same traversal rules now live in two places.
• I’d maybe add one more explicit test for the fallback behavior in findPlugins() when a top-level directory has no src/ and no nested plugin children, just to document why that legacy behavior is kept.

If you want, I can add a commit on top here.
