feat(pipeline): add comparative analysis scoring and GoReleaser brews section
1f5871bdcf399184e66d97e864217c5e6b15ae2f · 2026-03-24 20:30:03 -0700 · Matt Van Horn
- Create comparative.go with 6-dimension scoring (breadth, install friction,
auth UX, output formats, agent friendliness, freshness) out of 100 points
- Produces comparative-analysis.md with score table, gaps, advantages,
and ship/hold recommendation
- Update goreleaser.yaml.tmpl with brews section for Homebrew tap distribution
