Restrict dispatch before the privileged workflow starts.

A user with repository write access can dispatch this workflow on a branch they control. GitHub runs the workflow definition from the selected ref, so that branch can remove this step-level guard while retaining contents: write and id-token: write. npm trusted publishing identifies the authorized repository and workflow file, not a required branch. Use a main-only protected release entrypoint or deployment environment instead of treating this shell check as the security boundary. (docs.github.com)

Review comment at @.github/workflows/npm-publish.yml around lines 123 - 125:
Replace the shell-level GITHUB_REF guard as the security boundary with a
main-only protected release entrypoint or deployment environment, so a workflow
definition from a user-controlled branch cannot start with contents: write or
id-token: write permissions. Keep the publishing job restricted to the protected
main release path.
