Pull request overview

This PR refactors useEstimateFees to expose a reusable React Query options builder, enabling fee estimation via queryClient.fetchQuery/ensureQueryData outside of React hook usage.

Changes:

• Added estimateFeesQueryKey and exported estimateFeesQueryOptions for fee estimation.
• Refactored useEstimateFees to use useQuery with the new query options (instead of wagmi hooks directly).
• Bumped package version to 1.5.0.
