Add agent-describe and agent-describe-derive under crates/ as workspace members. Configure release-plz to publish the library crates while keeping the binary crate unpublished. Update template/Cargo.toml to use a version dependency instead of an absolute path. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
