test(handlers): add coverage for plugins_listing.go

Fills gaps from #1488 not covered in plugins_test.go:
- parseManifestYAML: wrong-type arrays (numbers in tags/skills/runtimes),
  missing file (bare directory returns fallback name).
- listRegistryFiltered: bare plugin dir without plugin.yaml → fallback name.
- ListAvailableForWorkspace: runtime-lookup error → unfiltered registry.
- ListInstalled: nil docker → 200 []; with runtime-lookup → no panic.
- CheckRuntimeCompatibility: container-missing path; compat/incompat separation.
