Subject: [PATCH] chore: infer version from branch in release-publish workflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove manual version input - the workflow now extracts the version
from the selected release branch (e.g., release/v0.3.0 → 0.3.0).

Also adds validation to ensure it's run from a release/v* branch.
