Install Pareto on this Mac.

Requirements:

1. Work in the local macOS environment. Confirm `uname -s` returns `Darwin`.
2. Do not create a cloud container and do not ask me to choose a repository.
3. Find the attached or downloaded "pareto-connect.zip" (or a numbered download such as "pareto-connect (1).zip").
4. Extract it and run "Install Pareto.sh" locally with bash.
5. Never ask me to paste the Pareto API key into chat or the terminal command.
   Wait while I enter it into the private macOS prompt.
6. Do not modify my existing Claude, Codex, Cursor, or Pi configuration.
7. After installation, run `~/.local/bin/pareto doctor`.
8. Report whether Pareto text and tool checks passed and whether optional ATXP
   was detected.

If you cannot access my local Downloads folder or macOS Keychain, stop and say
that this is not a local installation session.
