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.
