feat: spring bones

[RocioCM]

This pull request introduces a new physics controller interface and adds support for spring bone parameters in the preview system. It defines a new SpringBoneParams type with validation, updates the preview messaging protocol to handle physics-related requests, and includes tests for the new type.

Preview system enhancements:

• Added IPhysicsController interface to preview-controller.ts and exposed it in IPreviewController, enabling physics-related operations in the preview API. (src/dapps/preview/preview-controller.ts, [1] [2] [3]
• Updated the preview messaging protocol to support the new physics namespace and the setSpringBonesParams method, allowing spring bone parameters to be set via controller requests. (src/dapps/preview/preview-message.ts, [1] [2] [3]

Spring bone parameters implementation:

• Introduced the SpringBoneParams type and its validation schema, including constraints for each parameter and an optional center field. (src/dapps/preview/spring-bone-params.ts, [1] [2]
• Exported spring-bone-params from the preview module for external usage. (src/dapps/preview/index.ts, src/dapps/preview/index.tsR10)

Testing:

• Added unit tests for SpringBoneParams, covering validation logic and boundary cases. (test/dapps/preview/spring-bone-params.spec.ts, test/dapps/preview/spring-bone-params.spec.tsR1-R52)
