Description
Builds on top of #4576 to finalize Metro manifest hashes for native cache workflows.
The main change is that manifest hashes are now produced from Metro's serialized bundle output instead of being derived during the earlier manifest generation path. That matters because Metro dev builds lazily compile federated entrypoints, exposes, and shared modules only after they are requested for a platform. Computing hashes from serialization gives us the final emitted bundle content in both production bundling and dev-server requests.
This PR also makes platform-scoped dev manifest requests warm the required federated modules before returning
mf-manifest.json, which enables testing federated module caching during development instead of only after production bundle output exists.In scope:
metroCorePlugin.shared.importresolve through the configured shared key while loading the actual import target.Validation run locally:
