giant analyze prep/submit previously defaulted the run directory to
next to the rollout parquet on /ceph. Default it instead to
<cwd>/analysis_runs/analysis_<id> so it lands inside the portal repo
checkout (/work) — gitignored, --run-dir still overrides it.
derive_run_dir/prep gained a default_base param; library callers that
don't pass one keep the old parquet-relative fallback.
Adds plot_kl_bars/plot_kl_bars_pl (numpy/polars variants) for ranking which
target dimension or pdg/material stratum drives KL regressions, with the
same kl*n group capping as plot_marginals. Switches existing histogram
plots to step-type/log-scale. Adds sample_frac to load_predicted_local for
subsampling large predict parquets.
