docs: add release notes for combined nonce RPC methods
Document the new MuSig2RegisterCombinedNonce and MuSig2GetCombinedNonce RPC
methods in the v0.21.0 release notes. These methods enable coordinator-based
signing patterns as an alternative to the standard MuSig2RegisterNonces
workflow.
What changed, and why it matters
This commit only adds documentation to the release notes describing two new MuSig2 RPC methods. It does not change any code, cryptographic logic, or API behavior. There is no security issue in the commit itself.
No security action required. Review the actual implementation PR #10436 separately if assessing the security of the new MuSig2 coordinator-based signing RPCs.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit is a documentation-only change to docs/release-notes/release-notes-0.21.0.md, adding an 8-line release note for MuSig2RegisterCombinedNonce and MuSig2GetCombinedNonce RPCs introduced in PR #10436. The diff contains no executable code, no protocol changes, and no bug fixes.

## RPC Additions
+* [Added support for coordinator-based MuSig2 signing
+ patterns](https://github.com/lightningnetwork/lnd/pull/10436) with two new
+ RPCs: `MuSig2RegisterCombinedNonce` allows registering a pre-aggregated
+ combined nonce for a session (useful when a coordinator aggregates all nonces
+ externally), and `MuSig2GetCombinedNonce` retrieves the combined nonce after
+ it becomes available. These methods provide an alternative to the standard
+ `MuSig2RegisterNonces` workflow and are only supported in MuSig2 v1.0.0rc2.
