feat(primordials): add Error subclass constructors

The audit script (run from socket-repo-template against this build's
dist/) flagged `new TypeError(...)` as the only Error subclass actually
constructed in src outside of vendored external/ code, and a follow-up
grep confirmed AggregateError / RangeError / SyntaxError / ReferenceError
appear in vendored copies but not in src today. Add all seven standard
subclasses now so the surface is complete and audit reruns are quiet.

- AggregateErrorCtor
- EvalErrorCtor
- RangeErrorCtor
- ReferenceErrorCtor
- SyntaxErrorCtor
- TypeErrorCtor
- URIErrorCtor

Bump to 5.28.0 (additive).
