pdg_contribution_table_pl sums real/generated total deposited energy and
total step_length per pdg species over the whole file (pure lazy polars
group_by, no post_pos reconstruction needed for these scalars). Adds
plot_pdg_energy_share/plot_pdg_length_share, each rendering two pies
(real vs generated) so the per-species breakdown can be compared directly,
plus a matching notebook section.

sum(step_length) per event_id, alongside the existing total deposited
energy, since path length and energy deposit aren't interchangeable once
tracks scatter. Adds plot_total_length and a matching notebook cell.

Aggregates giant predict --coord local output per event_id into total
deposited energy, longitudinal/transverse shower profiles, and shower-max
depth, reconstructed into world-frame physical units (mm, MeV). Streams the
file in two polars passes rather than building a SampleCollection, since
per-event sums would be corrupted by row subsampling on these large files.

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.

ruff removed unused imports across analysis.py and several test files.
ty caught a wrong dict[int, int] annotation on StreamingStepsDataset's
mat_map (materials are strings) and a real bug in steps_to_parquet.py
where --compression none passed None to polars' write_parquet, which
only accepts the literal "uncompressed". Also narrows a few
Optional-typed attributes (ddpm_schedule, Normalizer.mean/std) with
asserts and aligns __getitem__'s parameter name with torch's Dataset
base class.

load_predicted_local now reads predict parquet via a lazy polars scan with
column projection pushed into the reader, instead of materializing the
whole file as a pandas DataFrame. Also adds marginal_table_pl and
constraint_report_pl, polars-native duplicates that read straight from a
predict parquet path/LazyFrame and stay lazy per (group, dim) pair, so
peak memory is one column slice rather than the whole SampleCollection.

Provides stratified marginal comparisons, joint-structure checks (correlation
matrices, physically-coupled pairwise plots, direction alignment), and
physical-constraint validation (unit-norm directions, non-negative raw
targets) for a trained model's generated samples, building on the aggregate
marginal/KL check already in giant.validate.
Supports two entry points: live sampling against a checkpoint + val data
(load_model_bundle/collect_samples), or loading a precomputed
`giant predict --coord local` parquet directly (load_predicted_local) without
needing the checkpoint at all. Predict output is now tagged with parquet
schema metadata so the loader can verify a file's format and reject
coord=global or untagged files with a clear error instead of guessing from
column names.
Also extends the config git-hash mismatch warning (added for --config
loading) to checkpoint loading: both `giant predict` and
analysis.load_model_bundle now look for a config.toml next to the checkpoint
and warn (without failing) if it was generated from a different git commit.
