chore: Item 9 — retire ReScript guidance → AffineScript (#16)

## Estate Tech-Debt — Item 9 (ReScript→AffineScript CI-text sweep)

Rewrites guidance/policy text that recommended **ReScript** as the
TypeScript/Python replacement to recommend **AffineScript** instead, per
the
estate language policy (RS/TS/JS → AffineScript → typed-wasm).

### Scope
- ✅ In scope: "use ReScript instead" guidance, `Rust/ReScript`
migration-guide
  phrasing, `Rust or ReScript` policy text.
- ⛔ Out of scope (intentionally untouched): any `rescript`-named
path/dir and
ReScript **adapters** (e.g. proven). That work is preserved intact and
usable
for the ReScript ecosystem — only the forward-looking recommendation
changes.

Mechanical, reviewed substitution; residual in-scope occurrences
verified 0.
