Developed cached volume support for the topolvm/topolvm repository, introducing a new volume type to enable caching-backed storage workflows. The implementation involved adding a 'C' type to the VolumeType and OpenTarget constants, as well as refactoring thin-volume detection logic to rely on volume attributes rather than pool presence, which improved accuracy in identifying cached logical volumes. Comprehensive tests were added to validate the new functionality and ensure regression safety. This work, completed in Go and focused on system programming and volume management, addressed issue #1003 and established more reliable and efficient provisioning paths for environments utilizing cached storage.
