The current Cloudflare adapter is an experimental version that would benefit from the work of a person familiar with Cloudflare’s APIs (Workers, Workflows).

packages/cloudflare/src/toCloudflare.ts still has placeholder run IDs, blank event names, and throws for sendSignal, waitForSignal, and nested workflow invocation. Implement these pieces (mapping Cloudflare’s APIs to StepKit’s) and add an integration example under examples/cloudflare. This is mostly glue code plus docs.
