Mechanism to specify input source location to find `package.json` instead of output source location when determining module format

nodenext, ts2351, construct

🕗 Version & Regression Information

• This is the behavior in every version I tried, and I reviewed the FAQ for entries about "A default import of a commonjs module with a default in a esm file doesn't seem to be the default export of that module when module is node16 or nodenext".

🙂 Expected behavior

It succeeds.

Additional information about the issue

• This issue requires a composite project, NodeNext, a package boundary, a default export, and a parent directory with a file package.{json, json5, yaml} without type: module.
  • Please note that import default inside foo's package boundary works.
  • One can delete the provided package.json after installing and run node_modules/typescript/bin/tsc --build tsconfig-base.json to test without package.json present.
  • One can see other package extensions trigger the bug by mv package.json package.yaml and pnpm run tsc.
• This is not a CommonJS project. It doesn't matter that there is a parent package.json without it. Node doesn't even read package.yaml.
  • This is from a real-world monorepo where there is a root pnpm package.json5 for cross-package scripts.

Bắt đầu với bản tái hiện typescript-nodenext-bug được liên kết: chạy npm install và npm run tsc, sau đó kiểm tra tsconfig-base.json cùng các biến thể package.json, package.json5 và package.yaml được mô tả trong issue. So sánh kết quả định dạng module NodeNext khi metadata của package cha có mặt hoặc không có; được xem là hoàn tất khi bản tái hiện thành công mà không có TS2351.
