Summary

• Add PR preview, main snapshot, stable GitHub Packages/npm publish, release doctor, and GitHub Pages jobs to the pipeline-owned workflow.
• Sync package scripts from pipeline.js and commit the pipeline task lock.
• Keep pnpm-first README examples and route development checks through generated pnpm run pipeline:* scripts.
• Add a small README-backed Pages build task until @async/pipeline owns README-to-Pages generation.
