Experimental updating without full reinstall.
Updates dotfiles by syncing configuration files to home directory.

Options:
  -f, --force      Force check all files even if no new commits
  -p, --packages   Enable package checking and building
  -n, --dry-run    Show what would be done without making changes
  -v, --verbose    Enable verbose output
  -h, --help       Show this help message
  -s, --skip-notice Skip notice about script being untested
      --non-interactive Run without prompting for user input

This script updates your dotfiles by:
  1. Auto-detecting repository structure (dots/ prefix or direct)
  2. Pulling latest changes from git remote
  3. Optionally rebuilding packages (if -p flag is used)
  4. Syncing configuration files to home directory
  5. Updating script permissions

Ignore file patterns support:
  - Exact matches (e.g., 'path/to/file')
  - Directory patterns (e.g., 'path/to/dir/')
  - Wildcards (e.g., '*.log', 'path/*/file')
  - Root-relative patterns (e.g., '/.config')
  - Substring matching (prefix with '**', e.g., '**temp' matches any path containing 'temp')
