These bootstrap scripts resolve the latest published release via the GitHub Releases API, download the single packaged zip artifact to a temporary directory, extract it, and then run the existing installer. The installer finds your Python interpreter, copies hook scripts to `~/.claude/hooks/drachometer/`, registers them in `~/.claude/settings.json`, creates the database, and runs a smoke test.
