Malte UblandClaude Opus 5.5 f176de2124 Construct CommonJS constructor functions imported through a member alias ...

A package that exports a constructor function whole and also as a named member (`exports = module.exports = Client; exports.StatsD = Client`, the statsd-client shape) could not be constructed from TypeScript: `new StatsD(...)` was refused as "constructing values other than classes declared in the program", and a bare reference had "no lowering".

- `exports = module.exports = value` is now the module's whole export, and it rebinds `exports` too, so members attached through `exports` afterwards are exported. The fresh-table reset `exports = module.exports = {}` keeps its own handling.
- An `import { name }` or a top-level `const { name } = require(...)` of a member written once as `exports.<name> = <binding or primitive literal>` on such a module reads that value, following `module.exports = require("./x")` re-exports. The checker gives these bindings a synthesized property symbol, so the module's statements answer.
- Construction then takes the existing checked path for JavaScript functions: prototype methods, `util.inherits` between two constructor functions, and `Parent.call(this, ...)` behave as in Node.
