feat(FN-3299): auto-install bundled runtime plugins on first save

Hermes / OpenClaw / Paperclip runtime cards in Settings now lazily
register themselves on first Save instead of failing with `Plugin
"fusion-plugin-...-runtime" not found`. The CLI also bundles each
runtime plugin (with @fusion/plugin-sdk inlined via esbuild) into
dist/plugins/<id>/bundled.js so npm/npx-installed Fusion can load them
without the workspace SDK dependency.
