Explore GitHub Actions for CI Testing of macOS Dotfiles #39

Explore the viability of using GitHub Actions to add CI-style testing to this dotfiles repo.

Since these dotfiles are primarily for setting up a macOS development environment, the challenge is finding a practical way to test workflows and configuration that are specific to macOS. Potential directions include:

• Use GitHub Actions' macOS runners to validate setup scripts against a clean environment.
• Identify which parts of the bootstrap/setup process can be realistically tested in CI (e.g., verifying presence of required binaries, linting configs, validating shell syntax).
• Consider ways to simulate or stub macOS-specific behaviors that aren’t easily testable in a CI runner.
• Define a baseline of 'essential' checks vs. more advanced or nice-to-have ones.
• Ensure that tests run quickly and don’t duplicate effort better spent in manual/VM testing.

The goal is not to make everything 100% testable, but to establish a framework that catches common errors early and improves confidence in changes to the repo.

It's quite likely that we may only want/need to run this for certain 'core' workflows like the bootstrap process/etc; and even then, only when those specific files (or things they reference) change.
