Google Chrome

Install Google Chrome 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 `google-chrome`. 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 `Google.Chrome`.
   - Linux: download the official package from https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb and install it with the system package manager (this adds Google's apt repository for future updates — tell me that before installing).

3. Check whether Google Chrome 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 version on macOS, `winget list Google.Chrome` on Windows, `google-chrome --version` on Linux) and show me the output.

Do not change my default browser or any of my settings unless I ask.

After installation, guide me through:
- Sign in to Chrome with my Google account and decide whether to turn on sync
- Import bookmarks and passwords from my previous browser if I want them
- Decide whether Chrome should be my default browser
- Review privacy settings (Safe Browsing level, ad privacy)
