support installation via brew formula

[pirafrank]

Should we add an option so that poof can be installed via Homebrew? Thinking of this as it may improve accessibility and ease of installation for developers using Homebrew in their workflows.

Rationale

Many users already use to install CLI tools through Homebrew for consistency, ease of upgrades, and automated provisioning in development environments (e.g., using Brewfile). Adding a Homebrew formula would also improve discoverability of poof.

What we should do

• Create and maintain a Homebrew formula in a tap (e.g., pirafrank/homebrew-poof).
• Optionally, submit it to homebrew-core if the project meets the guidelines.
• Provide pre-built binaries or configure the formula to build from source.
• Add installation instructions to the README

How to do it

Item	Value
Tap repo name	pirafrank/homebrew-poof
Formula file name	poof.rb
Install via tap	brew install pirafrank/poof

Sample poof.rb content:

class Poof < Formula
  desc "Command-line tool for awesome things"
  homepage "https://github.com/pirafrank/poof"
  url "https://github.com/pirafrank/poof/archive/refs/tags/v0.4.0.tar.gz"
  sha256 "PUT_REAL_SHA256_HERE"
  license "MIT"
  head "https://github.com/pirafrank/poof.git", branch: "main"

  # If Poof is built in Go, use this block:
  depends_on "rust" => :build
  
  def install
    system "cargo", "install", *std_cargo_args
  end

  test do
    # Replace with a real test command if available
    assert_match "poof", shell_output("#{bin}/poof --help")
  end
end

Note: we should consider poof is cross-platforms on Linux and macOS, supporting both arm64 and x64, and having musl builds on Linux as well.

Installation commands

brew tap pirafrank/poof
brew install poof

Considerations

The tap repository pirafrank/homebrew-poof must contain only one formula file so that brew install pirafrank/poof can be used as installation command (instead of brew install pirafrank/poof/poof).
