Contract
- assert allowStaleOnFetchRejection: true returns stale data on fetchMethod rejection while default fetch rejects
- assert allowStaleOnFetchRejection: true resolves to undefined on cache miss when fetchMethod throws
- assert in-flight fetch coalescing causes single AbortSignal to reject all callers unless ignoreFetchAbort: true is configured
- assert allowStaleOnFetchAbort: true immediately resolves with stale data when AbortSignal triggers
- assert cache.set on existing key triggers dispose with reason 'set' unless noDisposeOnSet: true is configured
- assert cache.set on existing key resets TTL start time unless noUpdateTTL: true is configured
- assert forceFetch rejects with Error when fetchMethod returns undefined while fetch resolves to undefined
