Module Federation + Rsbuild — Dev Loop Gotchas

Operational reference for the five things that bite teams adopting Module Federation 2.0 on the rsbuild stack. None of them block adoption; all of them silently cost time if you don't see them coming. Cross-origin HMR, TypeScript across federation boundaries, the rspack-escape-hatch config shape, MF 1.0 vs 2.0 documentation drift, and the smaller-than-Vite plugin ecosystem. Reference for the augment-it rewrite (and anywhere else in the family that picks the same substrate).
