feat: Implement depth surface strip cleanup and organize tool CLI

- Added a proposal for depth surface strip cleanup, detailing the rationale and changes to the depth plane and cutout nodes.
- Created specifications for the new cleanup requirements, including scenarios for strip removal and boundary edge detection.
- Developed tasks for implementing shared strip detection logic and integrating new interfaces for depth nodes.
- Established a new CLI structure for organizing node groups and model commands, replacing old entry points with a more intuitive command structure.
- Introduced a prototype for panorama surface generation, including requirements for distance reconstruction and geometry node surfaces.
- Added comprehensive tests for depth strip cleanup functionality, ensuring correct behavior for various mesh topologies and edge cases.
