chore: retire ReScript guidance text → AffineScript (Estate Item 9) (#5)

Estate language policy: RS/TS/JS → AffineScript → typed-wasm. This rewrites
guidance/policy text that recommended ReScript as the TypeScript/Python
replacement so it now points at AffineScript.

Scope guard (deliberate): rescript-named paths and ReScript adapters are NOT
touched — that work is preserved intact for the ReScript ecosystem. Only the
forward-looking "use ReScript instead" recommendation is updated.
