fix: enable agent-lifecycle-toolkit (altk) on Python 3.14

agent-lifecycle-toolkit 0.10.x dropped its own requires-python <3.14
cap (now >=3.10) and does not depend on OpenDsStar, so the
`python_version < '3.14'` gate on the altk extra is stale.

- Remove the python_version < '3.14' marker from the altk extra in
  langflow-base, keeping the macOS x86_64 platform exclusion.
- Regenerate uv.lock: agent-lifecycle-toolkit resolves on 3.14 and
  coexists with the onnxruntime>=1.26 langflow forces there
  (verified agent-lifecycle-toolkit 0.10.1 + onnxruntime 1.26.0).

OpenDsStar (the separate OpenDsStarAgent component) stays gated: all
its releases still cap requires-python at <3.14 upstream.
