feat: migrate grepo CLI from scripts monorepo to standalone package

Production-grade AI-powered GitHub repository management CLI.
Generates READMEs (two-phase analysis+generation), topics, descriptions,
and analyses using Gemini with Effect-TS service architecture.

Includes Mermaid diagram validation with mmdc and auto-fix loop.
Replaces Bun-specific APIs with Node.js equivalents for portability.
