A dotfile management tool that creates intelligent symlinks
between configuration files in a git repository and their expected locations.

Features:
- Directory-based operation (like git, npm, make)
- Simple .cfgman.json configuration format
- Built-in gitignore-style pattern matching
- Flexible link mappings with file/directory-level control
- Safety features: dry-run mode, confirmations, cross-repo protection
- Zero external dependencies
