Description
sync() should stop fetching full Guardian state when Guardian has no newer canonical state than the local account.
Add a lightweight authenticated API that returns the latest canonical nonce for an account, and update client sync to use it as a pre-check:
- run the normal network sync first
- fetch Guardian’s latest canonical nonce
- if guardian_nonce <= local_nonce, skip the Guardian state fetch
- if guardian_nonce > local_nonce, continue with the existing full sync flow
Scope:
- add the new HTTP/gRPC endpoint in Guardian
- add support in crates/client and packages/guardian-client
- update multisig sync to use the nonce pre-check
Acceptance criteria:
- Guardian exposes the latest canonical nonce for an account
- sync skips full Guardian fetches when Guardian is not ahead
- existing sync behavior is unchanged when Guardian is ahead

Research direction
Start by tracing the existing sync flow in crates/client, packages/guardian-client, and the multisig sync code. Review how Guardian’s HTTP/gRPC APIs are exposed, then verify the nonce pre-check against the acceptance criteria: unchanged behavior when Guardian is ahead and no full state fetch when it is not.
