Transform install.sh and restore.sh from location-dependent scripts into
portable tools that can be executed from anywhere. This major enhancement
improves usability, maintainability, and user experience.

Key improvements:
- **Portability**: Scripts now detect their location automatically using
  absolute path resolution, eliminating the requirement to run from specific directories
- **Shared utilities**: Created macos/utils/logging.sh with standardized logging
  functions (print_header, print_step, print_action, print_success, etc.) to
  eliminate code duplication between scripts
- **Native dry-run**: Simplified dry-run implementation by leveraging native tool
  capabilities (stow -n) instead of manual simulation, reducing maintenance overhead
- **Enhanced UX**: Added comprehensive backup directory status reporting and
  cleanup commands after restoration completion
- **Output visibility**: Fixed eval statement that was suppressing stow's verbose
  output, ensuring users can see problematic files and operations
- **Accurate counting**: Fixed manifest file counting logic that incorrectly
  included backup-manifest.json in dotfile counts

Technical changes:
- Replace hardcoded PWD with dynamic STOW_DIR detection
- Consolidate duplicate dry-run conditional logic throughout restore.sh
- Standardize all user-facing messages using shared logging functions
- Add intelligent backup directory analysis distinguishing metadata from dotfiles
- Improve error handling and exit code management

Relocate backup directory from `~/.dotfiles-backup-<timestamp>` (clutters
home directory) to `~/.backup/dotfiles/<timestamp>` for better organization
and cleaner home directory structure.

Changes made:
- **install.sh**: Update backup directory path construction and add robust
  error handling for directory creation conflicts
- **restore.sh**: Update search patterns, path construction, and timestamp
  extraction logic to work with new directory structure
- **Error handling**: Add checks for existing files blocking directory
  creation and permission issues
- **User messages**: Update all references to show new backup location

Benefits:
- Cleaner home directory (no scattered `.dotfiles-backup-*` directories)
- Organized backup structure under dedicated `.backup` directory
- Consistent with common backup location conventions
- Maintains full backward compatibility for restore operations

Tested successfully:
✅ Backup creation in new location
✅ Backup listing and discovery
✅ Restoration from new backup structure
✅ Error handling for edge cases
✅ Cleanup command path accuracy

Add comprehensive VM-only testing instructions to prevent issues like git
configuration corruption that can occur when running installation scripts
directly on the host machine.

Changes made:
- **CLAUDE.md**: Add critical warnings about VM-only testing with practical
  SSH examples using typical UTM IP patterns (192.168.64.x)
- **development-environment.md**: Consolidate duplicate testing sections,
  add practical SSH shortcuts with $(whoami) pattern, and emphasize safety principles
- **Quick reference**: Document that VM username usually matches host user
  and UTM typically assigns 192.168.64.x IP addresses

Key improvements:
- Prominent warnings against testing on host machine
- Practical copy-paste SSH commands with realistic examples
- Consolidated documentation structure eliminating duplication
- Clear guidance for both Claude Code and developers

This prevents the git configuration issues we encountered and establishes
safe testing practices for future development.

@claude regarding your comments:

  1. .api_keys is not present in this repository, nor is it adopted via stow. It's simply created directly in user's home directory, so they can use it if they want to.
  2. These are dotfiles, backup retention policy is overkill considering we're only backing up configuration files (which are a few kb at maximum).
  3. There are no .env files in project, nor is there any need for them. Hence, no need to add them to .gitignore.
  4. Templates are for internal use only. Never utilized during dotfiles installation or linking.
  5. Shell startup performance optimization is something which will come later.

Response to Clarifications

Thank you for the detailed clarifications! You're absolutely right on all points. Let me address each one:

1. .api_keys Security Assessment - RESOLVED

  • You're correct - since .api_keys is created directly in the user's home directory (not in the repo), there's no security risk of it being committed
  • My concern was based on a misunderstanding of the file location
  • The current implementation is secure and appropriate

2. Backup Retention Policy - AGREED

  • You're right that backup retention would be overkill for dotfiles
  • Configuration files are small and the current backup system is proportionate to the need
  • The timestamped backup approach is perfect for this use case

3. .env Files - ACKNOWLEDGED

  • Confirmed there are no .env files in the project
  • No need to add them to .gitignore since they're not used
  • My suggestion was overly cautious

4. Templates - UNDERSTOOD

  • Templates are for internal use and not processed during installation
  • No validation needed since they're not part of the automated workflow
  • This makes sense for your architecture

5. Shell Startup Performance - NOTED

  • Acknowledged this is planned for future optimization
  • Current setup prioritizes functionality and comprehensive tooling
  • Performance tuning can indeed come later

Revised Assessment

With these clarifications, my security concerns are resolved and the architecture decisions make perfect sense. This is an excellent dotfiles implementation with:

  • Proper security practices - API keys handled correctly in user space
  • Appropriate scope - Backup system sized correctly for dotfiles
  • Clean architecture - No unnecessary files or policies
  • Future-ready - Performance optimization planned appropriately

The PR maintains its excellent rating. Thank you for taking the time to clarify these design decisions!
