Per FabledRulebook forgejo.md, toolchain versions live on the runner
image, not in the workflow. Two changes here, paired with the runner
image bump (RUFF_VERSION 0.9.7 -> 0.15.13 in CI-Runner/CI-python):
- Drop "ruff>=0.9,<1.0" from ci.yml's pip install — the runner image's
pre-installed ruff is authoritative now. Previously this constraint
matched the existing 0.9.7 in the image so pip never upgraded.
- Flip ruff.toml's target-version back to py314 now that the runner
has a ruff new enough to know about it.
Next bump path: edit RUFF_VERSION in CI-Runner/CI-python/Dockerfile,
'make push', done. No workflow churn.
