fix(vanilla): Snapshot<T> ignores branded primitive types

[pastelmind]

Related Issues or Discussions

Fixes #747

Summary

Add the 7 primitive types (string, number, boolean, undefined, null, symbol, bigint) to SnapshotIgnore, so any subtypes of these primitive types are ignored by Snapshot<T>.

This fixes a bug where branded/tagged primitive types (usually created by intersecting them with a faux object type) are incorrectly transformed when passed through Snapshot<T>.

This doesn't handle object-like branded/tagged types, but such types are less common in practice.
