[Feature] Homebrew installation support

[tillig]

Problem
On Mac, pip install doesn't work because Python avoids modification of the global set of packages. It specifically recommends using brew install to manage the package via Homebrew.

Proposed solution
Add a local deploy/homebrew/auto-memory.rb file. It would look something like this:

class AutoMemory < Formula
  include Language::Python::Virtualenv

  desc "Session memory recall for AI coding agents"
  homepage "https://github.com/dezgit2025/auto-memory"
  url "https://github.com/dezgit2025/auto-memory.git",
      tag:      "v0.2.0",
      revision: "" # fill after tagging
  license "MIT"

  depends_on "python@3"

  def install
    virtualenv_create(libexec, "python3")
    system libexec/"bin/pip", "install", *std_pip_args(prefix: libexec), "."
    bin.install_symlink libexec/"bin/session-recall"
  end

  test do
    assert_match "usage", shell_output("#{bin}/session-recall --help", 2)
  end
end

Update install instructions to be brew tap dezgit2025/auto-memory && brew install auto-memory for Mac.

Alternatives considered

• Instructions could be updated to use pipx instead of pip.
• Submit an official Homebrew formula to their repo instead of local hosting.

Additional context

It would be good to get the latest updates released to PyPI - none of the pip install or pipx install works right now on any of the latest code (#18).

I did discover you can use uv tool install "auto-memory[claude] @ git+https://github.com/dezgit2025/auto-memory@v0.4.0" to install things so maybe switching the instructions/README to that would be better?
