input+signrpc+lnwallet+multi: implement combined nonce support
Add CombinedNonce() and RegisterCombinedNonce() methods with full implementation
stack.
Interface and core implementation:
- input/musig2.go: Added methods to MuSig2Session and MuSig2Signer interfaces
- input/musig2_session_manager.go: MusigSessionManager implementation using
HaveAllNonces flag for state tracking (simplified, no extra fields)
- internal/musig2v040: Stub implementations returning ErrUnsupportedMethod
- Mock implementations (MockInputSigner, MockSigner, DummySigner)
RPC layer:
- lnrpc/signrpc/signer.proto: RPC method definitions and messages
- lnrpc/signrpc/signer.yaml: REST API endpoint mappings
- Generated protobuf code (all .pb.go files)
- lnwallet/rpcwallet/rpcwallet.go: RPCKeyRing client implementation
The proto types and RPCKeyRing are added together since RPCKeyRing implements
the Signer interface and requires proto types to fulfill the contract.
For v0.4.0, these methods return ErrUnsupportedMethod. Use MuSig2Version100RC2
to access these features.

What changed, and why it matters
This commit adds new experimental API methods to LND's MuSig2 multi-signature signing system, allowing a coordinator to register an already-aggregated combined nonce instead of each participant registering individual nonces. It is a feature addition, not a fix for a known security bug. The new RPCs are marked highly experimental and only work with the newer MuSig2 v1.0.0rc2 version; the legacy v0.4.0 implementation rejects them.
Recommended action
Treat this as a routine feature commit, not a security patch. Review the final implementation of the v1.0.0rc2 session's RegisterCombinedNonce and CombinedNonce for proper nonce validation, length checks, and mutual-exclusion enforcement before the experimental flag is removed. Ensure RPC authentication/authorization covers the new signer endpoints.
Security signals we found
01
New experimental RPC surface increases attack exposure for the signer service
02
Combined nonce registration bypasses per-nonce validation, relying on caller-provided aggregated nonce correctness
03
No input length validation visible in the diff for the 66-byte combined nonce field
04
Legacy v0.4.0 implementation explicitly returns ErrUnsupportedMethod, reducing risk of accidental misuse
Evidence from the diff
The change extends the MuSig2 signer interfaces and RPC surface with MuSig2RegisterCombinedNonce and MuSig2GetCombinedNonce. It updates the session manager to track a HaveAllNonces flag, adds stub unsupported-method returns for the v0.4.0 compatibility layer, regenerates protobuf/gRPC/REST/swagger code, and implements the RPCKeyRing client. No existing behavior is removed or altered; the new methods are additive and mutually exclusive with the existing per-nonce registration path.

+
+The following methods from the newer MuSig2 specifications are not supported in
+this legacy v0.4.0 implementation and will return `ErrUnsupportedMethod` if
+called:
+
+- `CombinedNonce()`: Returns error instead of the combined nonce.
+- `RegisterCombinedNonce()`: Returns error instead of registering a

+
+These methods are only available when using MuSig2 v1.0.0rc2 or later. To use
+these features, create sessions with `MuSig2Version100RC2` instead of
+`MuSig2Version040`.
