## Summary by CodeRabbit

* **Breaking Changes**
* Removed major Rust public APIs related to document/CRDT encoding,
synchronization, and document loading from the affected packages.
* **Chores**
* Migrated internal dependency usage to published crates and trimmed the
Rust workspace/feature surface.
* **CI/CD**
* Simplified the Rust CI pipeline by removing advanced testing jobs and
updating job dependencies.
* **Dev/Test/Bench**
* Removed associated benchmark and fuzzing artifacts and related
fixture/test utilities.
