What this post added

Introduces Conductor, a Gemini CLI extension that enables context-driven development by formalizing project context (product, tech stack, workflow) into persistent Markdown files. This allows for planning before coding, maintaining AI context with style guides and goals, safe iteration through plan reviews, team collaboration with shared context, and building on existing codebases by informing design decisions. Conductor supports 'brownfield' projects by creating foundational documents and updating context as projects evolve. It works by establishing context via `/conductor:setup`, specifying and planning new work with `/conductor:newTrack` to generate specs and plans, and implementing code via `/conductor:implement` which iterates through the plan.md file.
