Add Homebrew support for localpost installation

[moshe5745]

Feature Request: Make localpost installable via Homebrew to simplify distribution and installation for macOS and Linux users.

Context:
Currently, users must manually build or install localpost by cloning the repository or downloading a binary. Supporting Homebrew would streamline the installation process, making it easier for users to get started with a simple brew install localpost. Homebrew is a popular package manager, and adding support would improve accessibility and align with common CLI tool distribution practices.

Proposed Steps:

1. Create a Homebrew Formula:
   • Write a localpost.rb formula for the Homebrew tap.
   • Specify the latest release (e.g., use GitHub release tags or commit hash).
   • Include dependencies (e.g., Go, if needed for build).
2. Test Installation:
   • Verify brew install localpost works on macOS and Linux.
   • Ensure the binary is correctly placed and executable.
3. Submit to Homebrew Tap:
   • Create a pull request to homebrew-core or a custom tap (e.g., homebrew-localpost).
   • Follow Homebrew’s contribution guidelines: https://docs.brew.sh/How-To-Open-a-Homebrew-Pull-Request
4. Update Documentation:
   • Add installation instructions to README.md (e.g., brew install localpost).
   • Mention Homebrew in setup guides.

Example Formula (rough draft):

class Localpost < Formula
  desc "CLI tool for testing HTTP requests with YAML configurations"
  homepage "https://github.com/<your-username>/localpost"
  url "https://github.com/<your-username>/localpost/archive/refs/tags/vX.Y.Z.tar.gz"
  sha256 "<sha256>"
  license "<license>"

  depends_on "go" => :build

  def install
    system "go", "build", *std_go_args(ldflags: "-s -w")
    bin.install "localpost"
  end

  test do
    system "#{bin}/localpost", "--version"
  end
end

Acceptance Criteria:

• Users can install localpost via brew install localpost.
• Installation works on macOS and Linux (Homebrew-supported platforms).
• localpost --version runs successfully post-install.
• Documentation updated with Homebrew instructions.

Additional Notes:

• Consider hosting a custom tap (e.g., homebrew-localpost) if homebrew-core criteria are strict.
• Check for dependencies (go, yaml.v3, go-pretty, etc.)—ensure they’re handled.
• Test with a release binary to avoid requiring Go on user machines.
