fix(ci): split publish-runtime into tags-only + autobump (closes #351) (#352)

publish-runtime.yml has never fired since the .gitea port (0 rows in
action_run.workflow_id='publish-runtime.yml' ever), which is why PyPI
is still at 0.1.129 despite Gitea having a runtime-v1.0.0 tag.

Root cause hypothesis: Gitea Actions evaluates the on.push.paths filter
against tag-push events too (no path diff → workflow skipped). PR #349
made this visible by adding the paths trigger, but the same defect
existed for the originally-ported tags-only trigger on this Gitea version
— hence the runtime-v1.0.0 tag also never published.

Fix: split into two files, each with a single unambiguous trigger shape.

  - publish-runtime.yml          : on.push.tags only       (the publisher)
  - publish-runtime-autobump.yml : on.push.branches+paths  (NEW; the bumper)

The autobump file computes next version from PyPI latest, pushes
'runtime-v$VERSION' tag via DISPATCH_TOKEN (not GITHUB_TOKEN — needed
to trigger downstream workflows on Gitea), and exits. The tag push
then triggers publish-runtime.yml.

Test plan after merge:
  1. Push no-op commit to workspace/. Observe autobump fire, push tag.
  2. Observe publish-runtime.yml fire on the tag, publish 0.1.130 to
     PyPI, cascade to template repos.
  3. Verify 'action_run' shows >0 rows for both workflow_ids.

+# Why this file exists (issue #351):
+#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
+#   when both are bundled under a single `on.push` key. The result is
+#   that tag pushes get filtered out and `publish-runtime.yml` never
+#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
+#   because PYPI_TOKEN was absent (publishes would have failed anyway).
+#
+#   Split design:
+#     - publish-runtime.yml         : on.push.tags only        (the publisher)
+#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)

+# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
+# so concurrent workspace pushes serialize at the bump step. Without
