1Password

Install 1Password on this machine. Follow these steps in order:

1. Detect my operating system and CPU architecture and tell me what you found.

2. Pick the install method for my OS:
   - macOS: Homebrew cask `1password`. If Homebrew is not installed, tell me and ask whether I want it installed from https://brew.sh first — wait for my answer before touching Homebrew.
   - Windows: WinGet package `AgileBits.1Password`.
   - Linux: install from 1Password's official repository per https://support.1password.com/install-linux/ (tell me it adds the downloads.1password.com repository before installing).

3. Check whether 1Password is already installed. If it is, tell me the installed version and ask whether I want to upgrade or leave it as is.

4. Before running anything, show me the exact commands you intend to run and what they will download and from where, then wait for my approval.

5. After my approval, run the install, then verify it worked by reporting the installed version (the app's About screen or package listing) and show me the output.

Never handle my credentials: do not create, view, or enter any passwords or my Secret Key — setup steps that need them are mine to do.

After installation, guide me through:
- Sign in with my account — I'll enter my email, Secret Key, and master password myself
- Install the browser extension for the browsers I use
- Enable unlock with Touch ID / Windows Hello if I want it
- Decide whether to enable the SSH agent and CLI integration
