Does this only work on certain "archive"-ish rpc's?

I used this syntax as it's from web3-v2 (now just known as kit) which is what the bots will be using. it's meant to be illustrative for how those clients can injest this data.

Great work!
The approach of picking the last signature (the oldest) based on the assumption that the first PDA creation event contains the relevant fill event makes sense!
Nit: It might be helpful to add a small integration test case that explicitly validates the assumption about signature ordering and PDA creation ensuring that any changes in teh RPC behavior or spam signatures don’t inadvertently break the logic.functionality.
This PR shows how we can easily fetch fill status events & fill status without needing to fetch all past events from the spoke pool. It introduces 2 new scripts to help with this as well as a new function added to the solanaProgramUtils to accommodate this flow.
