chore: pin climate_ref_client as known-third-party for ruff isort

The generated client lives at the repo root after the docs notebook
runs `uvx openapi-python-client ... --output-path climate_ref_client`,
which makes ruff's isort heuristic flip-flop between treating it as
first-party (locally, dir present) and third-party (CI fresh checkout).
Pinning it as third-party keeps the import grouping stable across
environments and unblocks the pre-commit job.
