Subject: [PATCH] fix: skip the release job when there's nothing to publish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Release workflow runs on every push to main. On a merge with no pending
changeset (Dependabot, docs, chore), changesets/action still ran `publish`,
which tried to re-publish the current version. Since it's already on npm,
changesets 2.31.0 crashed parsing npm's "already published" response instead of
no-opping — red-X-ing every routine merge (e.g. run #27 from the #39 merge).

Guard the step: only run changesets/action when a changeset is pending or the
local version isn't the one published on npm. Routine merges now skip it; the
real release paths (open the version PR / publish the bumped version) are
unchanged.
