There was a problem hiding this comment.
I don't think we should merge this to master as it's tracking v0.20, rather we should create lnd-21-0 branch merge there and tag as v0.21.0-1?

This commit adds two new methods to the SignerClient interface: - MuSig2RegisterCombinedNonce: Registers a pre-aggregated combined nonce for a session. This is an alternative to MuSig2RegisterNonces and is used when a coordinator has already aggregated all individual nonces. - MuSig2GetCombinedNonce: Retrieves the combined nonce for a session after it becomes available. These methods are needed for coordinator-based MuSig2 signing workflows. Also updates lnd dependency to include sqldb v1.0.12.
