Implement, review, debug, and refactor TanStack Start React Server Components in React 19 apps.

Notes on drift observed during validation

Current RSC docs and blog use renderServerComponent, createCompositeComponent, CompositeComponent, and low-level Flight APIs from @tanstack/react-start/rsc.
Current Server Functions docs use .validator(...).
Some current RSC docs snippets still show older .validator(...).
Older official repo examples may still show renderRsc and older config shapes. Prefer the current docs above.
