## Summary
**What** — What changes are introduced in this PR?
This PR fixes a bug where async workflow steps with retry intervals would get stuck after the first retry attempt due to Bull queue jobId collisions preventing retry jobs from executing.
**Why** — Why are these changes relevant or necessary?
Workflows using async steps with retry configurations (e.g., `retryInterval: 1`, `maxRetries: 5`) would fail once, schedule a retry, but the retry job would never execute, causing workflows to hang indefinitely.
**How** — How have these changes been implemented?
**Root Cause:** Bull queue was rejecting retry jobs because they had identical jobIds to the async execution jobs that already completed. Both used the format: `retry:workflow:transaction:step_id:attempts`.
**Solution:** Modified `getJobId()` in `workflow-orchestrator-storage.ts` to append a `:retry` suffix when `interval > 0`, creating unique jobIds:
- Async execution (interval=0): `retry:...:step_id:1`
- Retry scheduling (interval>0): `retry:...:step_id:1:retry`
Updated methods: `getJobId()`, `scheduleRetry()`, `removeJob()`, and `clearRetry()` to pass and handle the interval parameter.
**Testing** — How have these changes been tested, or how can the reviewer test the feature?
Added integration test `retry-interval.spec.ts` that verifies:
1. Step with `retryInterval: 1` and `maxRetries: 3` executes 3 times
2. Retry intervals are approximately 1 second between attempts
3. Workflow completes successfully after retries
4. Uses proper async workflow completion pattern with `subscribe()` and `onFinish` event

## Examples
```ts
// Example workflow step that would previously get stuck
export const testRetryStep = createStep(
{
name: "test-retry-step",
async: true,
retryInterval: 1, // 1 second retry interval
maxRetries: 3,
},
async (input: any) => {
// Simulate failure on first 2 attempts
if (attempts < 3) {
throw new Error("Temporary failure - will retry")
}
return { success: true }
}
)
// Before fix: Step would fail once, schedule retry, but retry job never fired (jobId collision)
// After fix: Step properly retries up to 3 times with 1-second intervals
```
