resolve

Awaits a reactive expression and returns its first fully-settled value as a Promise. Pending async reads (createMemo returning a promise, etc.) are waited on; once the expression returns synchronously without NotReadyError the promise resolves with that value. If the expression settles with an error instead — including an async source that rejects — the promise rejects with it.

Must be called outside a tracking scope — it doesn't subscribe, it only resolves the current value once.
