Handle string root exports before iterating entries.

If a published package declares "exports": "./dist/index.js", Object.entries(pkg.exports) iterates the string's characters. The loader can then skip every character and report success without importing the entry. Normalize a string export to a "." entry before iterating.

Review comment at @tests/src/unit/builtPackages/loadEntries.mjs around lines 19
- 21:
Normalize string-valued pkg.exports to a "." root entry before the
Object.entries loop in the package entry loader; keep the existing handling for
object-valued exports so string root exports are imported instead of iterated
character by character.
