Pull request overview

This PR updates the PulsarConnection reconciliation flow to honor the AlwaysUpdatePulsarResource feature gate so that managed child resources can be re-applied even when they are already Ready=True (useful for upgrade remediation), and documents/exposes that behavior via Helm values and docs.

Changes:

• Continue connection reconciliation for “ready-only” child sets when AlwaysUpdatePulsarResource is enabled and at least one managed child resource is observed.
• Add unit tests covering always-update enabled/disabled behavior and ensuring the deletion guard behavior remains intact.
• Document reconciliation skip semantics and surface the feature toggle guidance in docs and Helm chart metadata.
