Fix release workflow repository dispatch payload

[Copilot]

The release GitHub Actions job was failing after publishing artifacts because the final gh api repository-dispatch command used invalid shell quoting. This updates the dispatch step so the release can complete and notify cloud-infra reliably.

• Root cause

  • The workflow built the package, generated docs, and created the GitHub release successfully.
  • Failure occurred in the final dispatch step due to mismatched quoting in the inline gh api arguments.

• Workflow change

  • Replaced the fragile -f/-F shell-quoted invocation with a heredoc JSON payload passed to gh api --input -.
  • Preserved the existing dispatch fields: tag, source repository, and triggering commit SHA.

• Result

  • The repository-dispatch call no longer depends on nested shell quoting.
  • The post-release notification path matches the intended payload structure for downstream consumers.
