* fix: migrate to Go module v2 for proper semantic versioning This change updates the module path from 'zotregistry.dev/zot' to 'zotregistry.dev/zot/v2' to comply with Go's semantic versioning rules. According to Go's module versioning requirements, major version v2+ must include the major version in the module path. The current module path 'zotregistry.dev/zot' only supports v0.x.x and v1.x.x versions, making existing v2.x.x tags (like v2.1.8) unusable. Changes: - Updated go.mod module path to zotregistry.dev/zot/v2 - Updated all internal import paths across 280+ Go source files - Updated configuration files (golangcilint.yaml, gqlgen.yml) - Updated README.md Go reference badge This fix enables proper use of existing v2.x.x Git tags and allows external packages to import zot v2+ versions without compatibility errors. Resolves: Go module import compatibility for v2+ versions Fixes: #3071 Signed-off-by: Luca Muscariello <muscariello@ieee.org> * fix: regenerate GraphQL files with updated v2 import paths The gqlgen tool needs to regenerate the GraphQL schema files after the module path change to use the new v2 imports.
