feat(types): Add wait and resolve types to tailor.workflow

[k1LoW]

Summary

Add TypeScript type definitions for workflow wait/resolve API (tailor.workflow namespace) to support human-in-the-loop workflows.

Added functions

• wait(key, payload?) - Suspends the current workflow execution and waits for an external signal to resume. Returns the result provided by the resolve() callback.
• resolve(executionId, key, callback) - Resolves a waiting workflow execution. The callback receives the wait payload and returns a result passed back to the wait() caller.

Usage

// In a workflow job function — pause and wait for approval
const result = tailor.workflow.wait("approval", {
  message: "Please approve this request",
  requestId: "req-123",
});

// In another function — resolve the waiting workflow
await tailor.workflow.resolve(executionId, "approval", (waitPayload) => {
  return { approved: true, approver: "admin" };
});
