Show HN: Treedocs: Documentation that automatically checks for staleness

Treedocs is a Swift CLI tool that generates and maintains automatically-checked documentation for repository structure, displaying file and folder descriptions in a readable tree format with visual indicators for stale or missing entries. The tool helps teams understand complex codebases faster by storing human-readable summaries in a version-controlled YAML file and can prevent undocumented changes through Git pre-commit hooks. Version 0.2.0 supports macOS 13+ and can be installed via Homebrew, Mint, or mise.
