Simplify PR build and preview workflow for OSS and teams

Simplify PR build and preview workflow for OSS and teams targets a $6.0B = 1,000,000 engineering teams x $6,000 ACV. Rationale: global number of engineering teams that would allocate budget for developer experience and PR automation tooling, with average team spend on DX/CI tooling of roughly $500/mo or $6k/yr. total addressable market with medium saturation and a year-over-year growth rate of 12-20% annual growth in developer productivity and CI/CD tooling spend driven by cloud-native adoption and remote engineering teams.

Key trends driving demand: Infrastructure as Code and reproducible dev environments -- makes per-PR ephemeral environments feasible to spin up automatically.; Rise of deploy-preview and preview-hosting platforms -- reviewers expect live previews inside PRs, creating demand for automated preview generation.; Increased OSS collaboration and maintainer burnout -- projects need tooling to reduce manual validation work per PR, boosting adoption.; GitHub Actions and marketplace integrations -- native hooks reduce friction to adopt PR automation tools..
