Complete NixOS rewrite: Transform Omarchy from Arch to declarative NixOS
- Replace shell script-based Arch installation with declarative NixOS configuration - Implement flake-based architecture for reproducible builds - Add modular system with feature flags (Docker, gaming, development, etc.) - Create declarative theme system with Tokyo Night and Catppuccin - Convert utility scripts to Nix packages with proper derivations - Add comprehensive development environments (Rust, Go, Python, Node.js, C/C++) - Implement Home Manager integration for user environment management - Add interactive installer with theme selection and feature configuration - Update documentation for NixOS-specific workflows and commands - Provide atomic updates with rollback capability This maintains all aesthetic and functional benefits of original Omarchy while gaining NixOS power: reproducibility, version control, and atomic updates. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
