/**
 * TypeScript 7 AST + Checker surface for test-only walks that need types.
 *
 * TypeScript 7.0 dropped the classic Compiler API (`createProgram` /
 * `getTypeChecker`). The native `typescript/unstable/sync` client exposes the
 * same Checker methods against the Go compiler, and `typescript/unstable/ast`
 * is the matching syntax tree.
