Persistence for docking component layouts

Our team has developed a basic sample application that demonstrates how to persist BentoFX docking component layouts across application sessions. We are currently formalizing the persistence design, documenting it, and refactoring our demo project to align with this design. Once this work is complete, we plan to submit the design, documentation, and example code to be reviewed for integration and inclusion in BentoFX.

Start by reviewing the existing sample application that demonstrates persistence for BentoFX docking component layouts. The work is complete when the persistence design is formalized and documented, and the demo project is refactored to match it for integration review.
