Pull request overview
Adds a new Soroban smart contract crate (contracts/cre) implementing a “KeystoneForwarder” with ownership, forwarder registry, config management, signature verification, receiver dispatch, and transmission tracking for CRE report forwarding.
Changes:
- Introduces the KeystoneForwarder contract, storage schema, and event types.
- Adds an extensive Rust test suite covering initialization, config lifecycle, signature validation, replay rules, and receiver behavior.
- Registers the new crate in the workspace (and lockfile) and adds a local Makefile for build/test.
