📝 Documentation

• Mark 4.0.0-alpha.12 as broken in the migration guide and document 4.0.0-alpha.13 as the re-publish.

🐛 Bug Fix

• Re-publish the partially failed 4.0.0-alpha.12 release as 4.0.0-alpha.13 so all packages are available at the same version.
• Publish packages serially with a small throttle delay to reduce the chance of npm provenance transparency log conflicts during monorepo releases.

🏠 Internal

• Add --concurrency 1, --throttle, --throttle-size 1, and --throttle-delay 5 to the Lerna publish command.
• Verified the release script loads with node --require tsx/cjs.

Pull request overview

This PR updates the release tooling and migration documentation to re-publish the partially-failed 4.0.0-alpha.12 release as 4.0.0-alpha.13, and to reduce the chance of npm provenance transparency log conflicts by publishing packages serially with throttling.

Changes:

• Update the Lerna publish invocation to use --concurrency 1 plus throttling flags.
• Add 4.0.0-alpha.13 to the migration guide and mark 4.0.0-alpha.12 as broken.
