Clear and concise description of the problem

As a user, I want to define an entrypoint as glob to avoid repeating myself, in addition to other defined entry points. This should also be reflected when writing exports.

Suggested solution

Allow entry points as glob, similar to tshy exports:

 entry: {
    ".": "src/index.ts",
    "v4/locales/*": "src/v4/locales/*.ts",
  },

Alternative

Write them manually/via script (which already works as workaround)

Additional context

To take it further, this could also be part of a tshy migration guide where the tshy exports map is taken, but that might be a separate issue.
