feat: implement Single Token Thread (STT) architecture foundation for IBC Host State, including HostState datum structure with version, ibc_state_root, and sequence counters, STT validator enforcing NFT uniqueness and monotonic state transitions, one-time NFT minting policy using UTXO reference for uniqueness, and updated Gateway tree rebuilding logic to query HostState UTXO via NFT instead of Handler AuthToken for canonical state guarantee

feat: implement ICS-23 proof generation for packet queries and verification methods in Mithril light client, including ICS-23 proof generation for all PacketService endpoints (commitments, acknowledgements, receipts, next sequence receive and ack), VerifyMembership and VerifyNonMembership implementations using ics23 library with proper proof specs matching Gateway's tree structure, and addition of ibc_state_root field to ConsensusState protobuf for storing the 32-byte Merkle root from Handler UTXO
