Evolving Spec-Driven Development: Conductor Now Supports Antigravity

Google’s Conductor has been converted from a Gemini CLI extension into a portable plugin for spec-driven development.

It now supports conversational use and works with Antigravity CLI and other tools, not just Gemini CLI.

The plugin keeps persistent Markdown project files like spec.md and plan.md to preserve shared context.

This update improves tool portability and backward compatibility while maintaining a structured development workflow.
