## Summary by CodeRabbit

* **Bug Fixes**
* Prevented unintended deletion of platform resource definitions during
migrations.
* Made timestamp generation resilient to environment differences to
avoid script failures.
* Made annotation steps tolerate failures so migrations continue if
overwrite fails.

* **Chores**
* Re-enabled automatic chart update path and added periodic
reconciliation to keep platform components up to date.

* **Refactor**
* Switched VM cloud-init to use native Kubernetes Secret for improved
compatibility.
