Rapid issue creation leads to errors

When I (or usually it's the agent) try to create multiple issues rapidly, I get this error:
```
Error: failed to insert issue: UNIQUE constraint failed: issues.id
```

To recreate the issue:
```bash
for i in {26..35}; do ./bd create parallel_$i 2>&1 & done
```

This seems to fix the issue (sleep inserted):
```bash
for i in {26..35}; do ./bd create sleep_$i 2>&1; sleep 0.1; done
```
