Audit and Streamline the Native Runtimes Release Process

Audit the cesium-native release process end to end and identify where AI or automation can reduce the human effort required to ship a release.

Focus areas:
- Identify repetitive manual checks, copy/paste work, and bottlenecks.
- Highlight places where AI could help draft, review, or verify release artifacts.
- Highlight places where automation could eliminate repetitive human steps.
- Break down an implementation plan

No files, tests, or entry points are named. Start by mapping the cesium-native release process end to end, recording manual checks, copy/paste work, and bottlenecks. Done means an audit of automation and AI opportunities plus a concrete implementation plan.
