test(handlers): add filesystem suite for ListRegistry (plugins_listing.go)

Tests listRegistryFiltered and ListRegistry endpoint:
  - empty dir → empty list
  - files (non-dirs) → ignored
  - single plugin with plugin.yaml → appears in list
  - runtime filter: claude-code plugin matches, hermes plugin excluded
  - universal plugin (no runtimes field) → always included
  - nonexistent dir → empty list (ReadDir error is non-fatal)
  - HTTP endpoint: GET /plugins → 200 with JSON array
