invalid instance status transition from error to pending_create

[Hdom]

Seeing this error fairly frequently after updating to 0.2.1

2026-06-23 14:36:49.481 [ERROR] failed to update runner status endpoint=github.com error=error updating instance: invalid instance status transition from error to pending_create pool_mgr=ORG pool_type=organization runner_name=runner-name source=map[file:/runner/pool/pool.go function:github.com/cloudbase/garm/runner/pool.(*basePoolManager).retryFailedInstancesForOnePool.func1 line:1476]

I believe that the error is here: https://github.com/cloudbase/garm/blob/main/runner/pool/pool.go#L1475
Fix should be to update InstanceStatusTransitions map to support this new code path.
