Walkthrough

Expanded the cache, scheduling, SSO, and storage adapter READMEs with implementation examples, required methods, installation steps, and Ghost activation configuration. Revised ESM and TypeScript build guidance by removing prior module-resolution and CommonJS compatibility details. Added Changesets metadata for patch updates to four adapter-related packages and recorded the documentation changes.
