Hi, this seems like a massive PR: 11k lines of code where only ~50% (pg.go + mocks) are directly marked as generated. Could you please say how much of this PR is generated using the go tools (including genAI)? I am asking since it seems that there are random code pieces which are unused, e.g., like half of pkg/types/chains/solana/lp_types.go : its const part, type EventIdl EventIDLTypes and its descendants; e.g., most of const entries in pkg/types/chains/solana/solana.go.
