What this PR does: Fixes mutation validation errors when using multiple remote queries inside a single $derived (e.g. $derived({ a: await queryA(), b: await queryB() })).

Done well: Wrapping the state mutations in untrack() is the right approach—it prevents Svelte 5 from treating these updates as reactive mutations during derived evaluation. The test case in query-derived-awaits covers the exact scenario. Clean changeset.

Note: The untrack in the reject path is equally important; good that both success and error paths are covered.
