Homebrew tap integration (#103)
Fixes #86 ## Summary - Add robust Homebrew tap update to release workflow - Add Homebrew installation option to README ## Release Workflow Improvements - Use Ruby instead of sed to update formula (handles nested `on_macos`/`on_linux` blocks correctly) - Validate all 4 checksums were updated (darwin/linux × amd64/arm64) - Fail build if any checksum update is missing - Skip commit on re-runs when formula is already up-to-date - Add verification step that greps for expected checksums ## Installation ```bash brew install wesm/taps/roborev ``` ## Related Changes - homebrew-taps: Updated formula with correct repo URL, Linux support, removed non-existent roborevd binary - roborev-docs: Added Homebrew section to installation page ## Test Plan - [x] Ruby update script handles nested blocks correctly - [x] Validation catches missing checksums - [x] Re-run safety (skips commit when no changes) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
