fix: use 'import type' syntax for type-only imports

microbundle's babel parser (@babel/parser@7.29.2) doesn't support
the inline 'type' modifier in destructured imports (e.g.
'import {type Foo} from ...'). Replace with separate
'import type { Foo } from ...' statements which are supported.

Fixes the release/publish-npm CI step that was failing on every
push to main with:
  SyntaxError: Unexpected token, expected "," (1:18)
