Rename the Go module path from code.gitea.io/gitea to git.mokoconsulting.tech/MokoConsulting/MokoGitea across the entire codebase. Scope: - go.mod module declaration - 2,235 Go source files (import paths) - Dockerfile WORKDIR and COPY paths - Swagger API templates - golangci.yml linter config External dependencies (code.gitea.io/gitea-vet, code.gitea.io/sdk/gitea, gitea.com/gitea/act, etc.) are intentionally NOT renamed — they are separate upstream modules. Closes #132 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
