startTransition

Solid 2.0 RC introduces a fundamentally async-first reactive system where async operations are integrated directly into the graph. This release also brings a new Rust-based compiler via `@solidjs/vite-plugin` and replaces SolidStart with an integrated 'start mode'.

This release focuses on internal CI/CD improvements, documentation corrections, and ensuring backport releases are correctly tagged as 'stable' in the package registry.
