Nested federation example

A multi-level Module Federation graph across bundlers:

AppBundlerRole
HostViteLoads Vite + Rsbuild remotes
Intermediate remoteViteExposes a panel; loads an Rspack leaf
Intermediate remoteRsbuildExposes a card; loads a Webpack leaf
LeafRspackExposes a card
LeafWebpackExposes a widget

Each app wires the MFDoctor adapter for its bundler. Build the suite, then gate cross-app facts:

pnpm demo:nested
# or:
pnpm test:nested

This path stays green. Consumers that use remoteEntry.js turn off config/remote-manifest-recommended (and Vite consumers also turn off reliability/version-first-offline-remotes) with comments — same suppression pattern as the mixed example.

For intentional red findings, use mixed issues or the one-rule showcase. Per-bundler build+MFDoctor demos: standalone findings.
