Prop 348: Add the Solana Metis USDC Remote Lease Controller to the Relayer Allowlist
Summary
This proposal adds the newly deployed Solana Metis USDC protocol's Remote Lease controller contract (nolus1xd9sgdu3lvwm0pzrxg3c3lxwvuwkc6jgzk43zkgzjnndrdp5shvsfv3uzp) to the Solana relayer allowlist (solana_allowed_relayers) in the IBC 02-client parameters on the Nolus Pirin mainnet (pirin-1).
Opening the controller's IBC channel to its Solana counterpart requires it to submit a MsgChannelOpenInit against the Solana light client. The chain's 02-client module treats the signer of that message as a relayer, and the allowlist is fail-closed: until the controller's own address is present, that message is rejected and the channel can never open.
Proposed Changes
MsgUpdateParams replaces the entire 02-client parameter set, so allowed_clients is restated here unchanged at its current on-chain value:
06-solomachine07-tendermint09-localhost
solana_allowed_relayers changes from the three existing relayer operator addresses to those same three plus the Remote Lease controller contract address:

Impact
The three existing relayer operators keep their access unchanged. The added address only grants the Remote Lease controller contract permission to submit Solana light-client channel-handshake messages for its own channel; it grants no other capability. No client type is added or removed, so the IBC connections and channels already in use on pirin-1 are unaffected.
By voting "YES" on this proposal, you agree to authorize the Solana Metis USDC Remote Lease controller to open its IBC channel on the Nolus Pirin mainnet.
