PreviewEntry class final

A single entry in the MagicPreviewCatalog.

Each entry pairs a human label and a URL-safe slug with a builder that renders the component (or component matrix) in isolation. The generated _previews.g.dart (auto-discovered from *.preview.dart files) returns a List<PreviewEntry> from a FUNCTION and feeds it to MagicPreview.register; nothing here is ever a top-level const list, so the release-mode tree-shaker can prove the whole catalog unreachable when the dev-only boundary in MagicPreview.registerRoutes folds dead.
