v0.4.5

Disruption handover fixes

• Fix sentinel startup when sentinel.enabled=true by removing the obsolete --mode argument. The chart's arguments are now checked against both binaries in CI. (#7)
• Honour the target Deployment or Rollout's minReadySeconds before counting a stand-in as available, in both reconciliation and eviction admission. (#9)
• Persist the eviction hold and relax it at readinessDeadlineSeconds even when replica changes or pod deletion-cost updates fail. Failed surges remain visible through status, events, and logs. (#10)
• Watch cordon and taint signals on every operator replica so standby replicas can make correct webhook decisions during multi-node disruptions. Workload reconciliation remains leader-gated. (#11)

Security

Update golang.org/x/net, gRPC, and OpenTelemetry dependencies past the identified advisories. (#8)

Upgrade

helm upgrade understudy oci://ghcr.io/kylan11/charts/understudy \
  --namespace understudy-system --version 0.4.5

There are no CRD schema or configuration changes from v0.4.4. Stand-ins now wait for the target's minReadySeconds; allow for that warm-up period when configuring readinessDeadlineSeconds. Upgrades from earlier versions should also follow UPGRADING.md.

• Image: ghcr.io/kylan11/understudy:0.4.5 (linux/amd64, linux/arm64)
• Helm chart: oci://ghcr.io/kylan11/charts/understudy, version 0.4.5
• API: apps.understudy.sh/v1alpha1, unchanged from v0.4.4

Thanks

Thank you to @0xmichalis for all five fixes and their regression tests.
