## Summary by CodeRabbit

* **Chores**
* Updated core build/dev tooling versions for more predictable installs
(analyzer and Turbo bumped).
* Relaxed workspace release gating by reducing minimum release age and
narrowing the list of tooling exclusions, streamlining staged upgrades.
* No runtime or public API changes; configuration and tooling-only
updates.
