Update module path from forge.lthn.ai/core/go-crypt to dappco.re/go/core/crypt. Migrate go-log, go-io, go-i18n imports to their new dappco.re/go/core/* paths with updated versions (core v0.5.0, log v0.1.0, io v0.2.0, i18n v0.2.0). Un-migrated modules (cli, go-store, go-inference) remain at forge.lthn.ai paths. Also fixes merge conflict marker and duplicate imports in crypt/openpgp/service.go, and updates CLAUDE.md to reflect new paths. Co-Authored-By: Virgil <virgil@lethean.io>
