Expose resource graph collection

[djgrant]

Summary

Expose collectResourceGraph and ResourceGraph from the root @notation/resource API while preserving top-level infrastructure declarations.

AWS helpers retain the original api(config), router(api), lambda(config), and schedule(config) contract. Resource groups register with the active graph during module evaluation. The collector type and registration wrapper are removed.

Graph collection is now an explicit API contract. There is no internal package entry point.
