Bump harbor to 0.20.0 across benchmark configs and regenerate locks

Move each benchmark to harbor 0.20.0 in lockstep so the eval resolves:
build.yaml harbor_requirement (the evaluator's --with harbor[modal]) and
target/pyproject.toml (the candidate's own harbor dep) must match, else
`uv run --project <target> --with harbor[modal]==0.20.0` is unsatisfiable.
uv.lock regenerated with `uv lock` (not hand-edited). Covers gaia,
officeqa, swe-atlas-qna, tau3.
