> [!NOTE]
> **Low Risk**
> Low risk dependency bump limited to `@metamask/json-rpc-engine`;
behavior changes are confined to upstream library updates and could only
surface via JSON-RPC request/response handling regressions.
> 
> **Overview**
> Updates the `@metamask/json-rpc-engine` dependency from `^10.2.1` to
`^10.2.3` and refreshes `yarn.lock` to resolve to `10.2.3`.
> 
> No application code changes; this is a dependency-only update intended
to pick up upstream fixes (notably around Snap account creation per PR
description).
