tsc wraps every CommonJS import in its helpers: `const events_1 =
__importDefault(require("events"))`, `const path =
__importStar(require("path"))`. cjs-tsc-interop.ts reads such bindings of
program modules as plain require bindings, so the helper declarations go
dead, but a builtin module is not a program module: its binding kept the
helpers live, and their probe of the module's top-level `this`
(`(this && this.__importDefault) ||`) failed at load ("property access
through top-level 'this'"). That is the shape of hundreds of tsc-compiled
files in a typical dependency tree.
A builtin carries no `__esModule`, so `events_1.default` is the module and
the namespace copy reads the module's members. When every reference has
that form, a package-file stage now respells the binding as the plain
require() of the builtin and `x.default` as `x`.
