/plugin  -->  Add marketplace  -->  provide repo URL

ls ~/.claude/plugins/cache/    # shows <marketplace-name>/ directory
   ls ~/.claude/plugins/data/     # may show <plugin>-<marketplace>/ directory

ls ~/.claude/plugins/cache/    # <marketplace-name>/ still exists (BUG)
   ls ~/.claude/plugins/data/     # <plugin>-<marketplace>/ still exists (BUG)
   cat ~/.claude/plugins/known_marketplaces.json   # marketplace entry correctly removed
   cat ~/.claude/plugins/installed_plugins.json    # plugin entries may still reference it
