feat: remove workflows namespace, keeping automations

Remove the duplicate 'workflows' namespace from the SDK. The preview-workflows
branch had both 'workflows' and 'automations' namespaces pointing to the same
/automations API endpoints. This commit removes:

- src/workflows/ (Workflows class, interfaces, specs)
- src/workflow-runs/ (WorkflowRuns class, interfaces, specs)
- src/workflow-run-steps/ (WorkflowRunSteps class, interfaces, specs)
- workflows property from Resend client
- workflow-related exports from index.ts

The 'automations' namespace (automations, automation-runs, automation-run-steps)
is preserved as the canonical SDK interface for these endpoints.

Also fixes a stale test describe name and test data in
parse-automation-to-api-options.spec.ts.
