3Eyes Family Safety installs a system-wide content filter and per-user
activity monitoring agent. The installer will:

  - Install /Applications/3Eyes.app
  - Add a system LaunchDaemon (runs as root, supervises the filter)
  - Add a per-user LaunchAgent (runs in each user's session)
  - Install the 3Eyes root certificate into the System keychain
    (required for HTTPS filtering)

This requires administrator authentication.
