[tkircsi]

• Update dir-staging documentation and configuration for v0.5.2 deployment strategy and storage features
• Documents the new v0.5.2 deployment strategy configuration (Recreate) required when using PVCs to prevent BadgerDB/SQLite lock conflicts during rolling updates.
• Updates CHANGELOG.md to include missing v0.5.2 features (SQLite PVC support, automatic /tmp mounting, deployment strategy), adds critical warnings in README.md for production PVC deployments, and enhances the comparison table to clearly show deployment strategy differences between Kind and production environments.
