Merge pr-verify.yml, pr-policy.yml, and pr-e2e.yml into a single
pr.yml with three parallel jobs (policy, verify, e2e). Benefits:
- Single concurrency group cancels all jobs on new push
- Consistent Node 24 across all jobs
- One file to maintain instead of three
The jobs still run independently (no artifact sharing) since pnpm
cache makes install fast and the upload/download overhead for
node_modules would negate the savings.
