Plugin detection now looks inside subfolders instead of only checking the top-level directory
When Claude Code scans a directory to see if it contains a plugin, it now recurses into subdirectories (skipping ones starting with a dot) instead of only checking the top level. If a directory itself looks like a plugin, it's reported as one; otherwise, it's reported as a collection, with separate lists of valid child entries and entries that were skipped.
This lets Claude Code find plugins that are nested inside folders rather than requiring plugin marker files to sit directly at the top level, and lets it report which nested items were recognized versus skipped.
