Feature request: Add Homebrew tap/cask for easier installation

Summary

It would be great to have CodexSkillManager available via a Homebrew tap so users can install and update it with a simple brew install command.

Current installation method

Currently users need to either:

1. Download releases manually from GitHub
2. Clone the repo and build from source with ./Scripts/compile_and_run.sh

Proposed solution

Create a Homebrew tap (e.g., dimillian/tap) with a cask for CodexSkillManager. This would allow installation via:

brew tap dimillian/tap
brew install --cask codexskillmanager

Benefits

• Discoverability: Users can find it via brew search
• Easy installation: Single command install
• Updates: brew upgrade handles updates alongside other apps
• Consistency: Many macOS developers expect Homebrew distribution

Notes

The app already uses Sparkle for auto-updates which is great, but Homebrew installation would make the initial setup much smoother. Other similar tools like CodexBar (steipete/tap/codexbar) already use this distribution method.

Happy to help test if you set one up!
