Description

This pull request updates the installation documentation for macOS to reflect the availability of Homebrew as the recommended installation method for tmpo. The documentation is reorganized for clarity and to provide up-to-date instructions for users.

Installation documentation improvements:

• Updated the README.md to direct users to platform-specific installation guides instead of listing binary downloads directly.
• Changed the macOS installation guide to make Homebrew the recommended installation method, providing detailed steps for installation, verification, updating, and uninstallation via Homebrew.
• Removed the "Homebrew (Coming Soon)" section and replaced it with actual Homebrew installation instructions.
• Clarified the uninstallation instructions in the macOS guide, distinguishing between Homebrew and manual binary removal.
