Update default scene configuration with new objects and adjustments

- Replaced object names and updated configurations:
  - Renamed `hole` to `star` and adjusted its position.
  - Renamed `peg` to `box`, added mass and size attributes, and refined position and randomization settings.
  - Added a new `cylinder` object with mass, radius, length, and position attributes.
  - Introduced a static `board` object with specified position and randomization settings.
- Improved structure and flexibility for object definitions in the default scene.
