## Summary by CodeRabbit

* **Chores**
  * Upgraded TypeScript toolchain to v5.9.3 across packages and tooling.
* Removed legacy ts-node and migrated developer tooling to newer
runtimes (tsx/SWC) where applicable.
* **Documentation**
* Updated developer CLI docs and runtime behavior notes to reflect the
new loader/runtime for running TypeScript files; no changes to public
APIs or end-user behavior.
