ci: release

[janishorsts]

This PR migrates the tap from a source-building bottle distribution to a binary-only distribution, fetching precompiled release assets directly from GitHub Releases.

Key Changes

1. Binary-Only Formula: Rewrote Formula/earth.rb to fetch precompiled binaries for macOS and Linux (Intel and ARM64). Removed the Go compilation dependency.
2. Simplified CI/CD: Removed all bottle-building targets, and related scripts from Earthfile.
3. Renovate & Checksum Automation:
   • Updated Renovate config to only watch the single version string in the formula and enable automerge: true for releases.
   • Created a GHA Release workflow that runs when Renovate opens a release PR. It fetches the new checksums from the checksum.asc release asset, updates the formula, and commits it back.
4. General Housekeeping: Updated the README with the correct repository casing/tap name and added ci.yaml to run tests on incoming PRs.

Summary of Changes

Hello @janishorsts, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the continuous integration and delivery pipeline for the EarthBuild Homebrew formula. It introduces a dedicated Earthfile to streamline build and quality assurance processes, alongside updating the earth formula to a new release candidate version. The update also expands support for Linux architectures and improves user experience by guiding them on necessary container runtime installations.

Highlights

• New CI/CD Earthfile: A new Earthfile has been added to the repository, defining CI/CD targets for building, linting, auditing, and styling the Homebrew formula. This centralizes and automates the quality checks for the formula.
• Homebrew Formula Update: The Formula/earth.rb file has been updated to reflect a new release candidate version (v0.8.17-rc-0), include bottle checksums for additional Linux architectures (arm64_linux, x86_64_linux), and update the default Buildkitd image used by EarthBuild.
• User Guidance for Container Runtimes: A new caveats section has been added to the Homebrew formula, providing clear instructions to users on how to install Docker or Podman, which are required for EarthBuild to function.

Code Review

This pull request updates the earth Homebrew formula for a new release and adds an Earthfile for CI. The formula update is mostly good, with style improvements and new Linux bottles. The new caveats section is a great addition. However, I've found a critical issue in the Earthfile where brew audit is called with invalid flags, which will cause the CI to fail. I've also suggested a couple of improvements in the formula file: one to make the bottle block more concise, and another to align the test command with the user-facing earthly command.

Code Review

This pull request migrates the earth Homebrew formula from a source-built Go formula to a binary-only distribution for macOS and Linux, updates CI/CD configurations, and adds a helper script to automate checksum updates. Feedback focuses on making the checksum update script more robust by handling pre-release versions, adding network timeouts, stripping leading asterisks from checksum filenames, and escaping regex curly braces. Additionally, the brew fetch command in the Earthfile should be updated to remove the --build-from-source flag since the formula no longer compiles from source.
