Pull request overview

This PR updates the project for a repository transfer (module path + release owner) and introduces a new --verify-ssl option to allow enabling TLS certificate verification (previously certificates were always skipped).

Changes:

• Add --verify-ssl CLI flag and wire it to tls.Config.InsecureSkipVerify.
• Update Go module path and GoReleaser GitHub owner for the new repository location.
• Adjust Makefile build commands to explicitly include multiple .go files.
