SPORK_3_INSTANTSEND_BLOCK_FILTERINGandSPORK_9_SUPERBLOCKS_ENABLEDhave been removed. These sporks were already effectively always enabled on mainnet but continued to gate behavior on test networks (testnet, regtest, and devnet). The associated functionality (InstantSend conflicting-block rejection and superblock payments) is now permanently enabled across all networks, and the sporks will no longer appear in thesporkRPC output.

getblocktemplatenow requires a fully synced node at superblock heights. This check is skipped on test networks. Previously it was gated bySPORK_9_SUPERBLOCKS_ENABLEDwhich was already always active on mainnet.
