Prop 215: Setup Archway IBC Auto-Forwarding

This proposal, if accepted, would establish the bech32 address prefix 'archway' as the IBC Auto-Forwarding prefix for SendToCosmos transactions. Any SendToCosmos transactions whose CosmosReceiver field begins with 'archway1' will be automatically forwarded to Archway Network over the IBC channel channel-145. Failed IBC transactions will result in tokens transferred to the equivalent address in the Gravity Bridge chain, requiring user intervention with the same Cosmos private key. When evaluating this proposal, the community should be confident that channel-145 is the official channel leading to the Archway Network, and that is the correct prefix for the Archway account addresses.
