docs: add comprehensive CLI documentation for issue #4

Added comprehensive documentation for core/cli including:

1. Complete CLI Reference (cli-reference.md)
   - All 30 commands with detailed descriptions
   - Subcommands, flags, and usage examples
   - Organized by category (Development, AI/ML, DevOps, etc.)

2. Build Variants System (build-variants.md)
   - How to create custom builds (minimal, dev, devops, ai/ml)
   - Three methods: import commenting, multiple main.go, build tags
   - External variant repos (core/php, core/ci)
   - Size optimization and compression tips

3. MCP Integration (mcp-integration.md)
   - Model Context Protocol server setup
   - All available tools (file ops, RAG, metrics, process mgmt, WebView/CDP)
   - Transport modes (stdio, TCP)
   - Security considerations and workspace restriction
   - Use cases and troubleshooting

4. Environment Variables (environment-variables.md)
   - All supported environment variables
   - Configuration file locations (user, project, registry)
   - CORE_CONFIG_* mapping system
   - Service-specific vars (MCP, RAG, ML, Git, etc.)
   - Best practices and troubleshooting

5. Updated Navigation
   - Enhanced cmd/index.md with categories and quick links
   - Updated mkdocs.yml with new documentation pages

Fixes #4
