Rename root, api and sdk module paths (imports, go.mod, go_package, ldflags, build scripts, buf configs) and regenerate protobuf/gateway code with the project's pinned toolchain. Wire identifiers unchanged. api gets a local replace for sdk; root/api/sdk require v0.1.0. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
