Distribute Rustipo through Homebrew

[fcendesu]

Summary

Distribute Rustipo through Homebrew so macOS users can install and upgrade the CLI with a standard package manager workflow.

Goals

• Provide a documented brew install path
• Keep the Homebrew distribution aligned with release artifacts
• Minimize manual maintenance when new releases ship

Acceptance Criteria

• Rustipo can be installed through Homebrew using a documented formula or tap
• Release artifacts and checksums required by the formula are available
• Installation docs explain the Homebrew workflow and update path
• Release/distribution notes document how the Homebrew formula is maintained

Notes

This should follow stable release artifacts and fits naturally after crates.io publishing and binary distribution are in place.

Homebrew tap is now live at https://github.com/fcendesu/homebrew-rustipo and verified with:\n\n- brew tap fcendesu/rustipo\n- brew install fcendesu/rustipo/rustipo\n- brew test rustipo\n\nThe in-repo source-of-truth formula was also updated to v0.11.0 in #147.

Automated tap sync is now wired into the release workflow in #148. Future releases will update https://github.com/fcendesu/homebrew-rustipo automatically when release assets are published, as long as the HOMEBREW_TAP_TOKEN secret is configured with write access to that repo.
