Publish locked Netlify production deploys after CI

[john-kurkowski]

Context

Production deploys currently come from GitHub Actions building the site and uploading dist directly to Netlify. That works, but it creates duplicate production deploy entries because Netlify also observes the production branch.

This changes the model so Netlify owns production builds, while GitHub Actions acts as the CI gate that publishes the matching Netlify-built deploy only after checks pass. Auto publishing is locked in Netlify, so production deploys are built but not made live until GHA explicitly publishes the deploy for the pushed commit.

Changes

• Re-enable Netlify production builds by removing the production ignore rule from netlify.toml.
• Replace the production artifact upload step in GitHub Actions with a publish step.
• Add src/scripts/publish-netlify-production-deploy.ts to:
  • poll Netlify production deploys for the current GITHUB_SHA
  • require the matching deploy to be for master and production
  • wait for in-progress deploys to become ready
  • fail on skipped, errored, unsupported, or missing deploys
  • publish the exact matching deploy via Netlify’s restore endpoint
• Add tsx as a direct dev dependency for running the TypeScript script in CI.
• Add tests for matching, publishing, waiting, failure, skipped deploys, and timeout behavior.

Test Plan

1. Open a PR from a non-master branch and confirm Netlify still creates a normal Deploy Preview.
2. Push or merge a commit to master and confirm Netlify creates a production deploy but does not publish it automatically while auto publishing is locked.
3. Confirm the GitHub Actions production deploy job waits for the Netlify deploy for the same commit SHA, then publishes that deploy after the required checks pass.
4. In Netlify’s deploy list, confirm the published production deploy corresponds to the same commit that passed GitHub Actions.
5. Confirm future production deploys remain locked until GitHub Actions publishes them; do not unlock Netlify auto publishing.
