imfozilbek 03705b5264 feat(guardian): add guardian package - code quality analyzer
Add @puaros/guardian package v0.1.0 - code quality guardian for vibe coders and enterprise teams.

Features:
- Hardcode detection (magic numbers, magic strings)
- Circular dependency detection
- Naming convention enforcement (Clean Architecture)
- Architecture violation detection
- CLI tool with comprehensive reporting
- 159 tests with 80%+ coverage
- Smart suggestions for fixes
- Built for AI-assisted development

Built with Clean Architecture and DDD principles.
Works with Claude, GPT, Copilot, Cursor, and any AI coding assistant.
