Homebrew / Xcode Tools Installation

Ensures Xcode tools are installed on macOS and ensures Homebrew is installed on either Linux or macOS

Overview

This script ensures macOS has tools like git by installing the Xcode command-line developer tools if they are not already installed. Then, on both Linux and macOS, it ensures Homebrew is installed.

Homebrew Requirement

Install Doctor relies on Homebrew for many tools that are currently only available via Homebrew. Removing the dependency would be a nice-to-have but there are currently no plans for supporting systems without Homebrew installed.
