Add comprehensive system enhancements and shell configurations
Following the μέτρον principle of durable, thoughtful solutions: Shell Configuration: - Add refined .zshrc with modular architecture - Include .p10k.zsh for Powerlevel10k prompt - Add .zprofile for login shell configuration - Update aliases with new dotfiles management tools System Management Tools: - safe-update.sh: System updates with rollback protection - detect-drift.sh: Configuration drift detection - system-health.sh: Comprehensive health monitoring - generate-lockfile.sh: Version tracking for reproducibility Documentation: - ARCHITECTURE.md: Philosophy and design rationale - USAGE.md: Practical guide and troubleshooting Other Updates: - Update symlinks.sh to manage all config files - Add .vimrc configuration - Create Brewfile.lock for version pinning These enhancements provide visibility, safety, and maintainability while following the prime directive of prioritizing durability. 🖖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
