Solid 2.0 RC: Async Becomes a First-Class Citizen of the Reactive Graph

Solid 2.0 Release Candidate rethinks async handling by integrating it directly into the reactive graph, eliminating the need for createResource, batch, and transitions. The new compiler, built on Oxc, delivers up to 355x speedups, and the Vite plugin's start mode replaces SolidStart, offering SPA, SSR, and server functions out of the box. With a migration guide and assistant, the ecosystem is ready for this major update.

The problem that never went away was async. Every framework, including ours, treated it as a condition that happened _to_ it. Something a synchronous core would have to weather.
