Cloudflare Introduces Isolated Testing for Workflows

🧪 Cloudflare has added local, isolated testing APIs for Workflows, enabling developers to introspect and mock workflow instances using the new cloudflare:test module. Available with @cloudflare/vitest-pool-workers v0.9.0+, the APIs (introspectWorkflowInstance and introspectWorkflow) let tests run offline inside the Workers runtime, mock step results and events, and preserve isolated storage for reliable, deterministic tests. This improves debug visibility, reduces flaky tests, and lets teams assert on intermediate steps without hitting external systems.
