// Bundlers and CJS interop can deliver the `typescript` module in a
// default-only shape (`{ default: ts }` without hoisted named exports).
// TypeScript 5/6 in that shape must still be routed to the in-process
// compiler API: the CLI fallback intended for TypeScript 7+ would run
// TypeScript 5's `tsc`, whose declaration emitter produces syntactically
// invalid unquoted export aliases (`export { x as a.b }`).
//
// `createProgram: undefined` is stubbed explicitly because vitest wraps
// factory mocks in a proxy that throws on missing exports, while a real
// default-only namespace returns `undefined`.
