v0.2.0 — CI allow-lists, per-split manifests, MLflow/W&B export

What's new

• verify --allow GLOB — allow-list expected churn in the CI gate: if every drifted path matches an allow glob, the gate still passes. --json gains gate and allowed fields.
• snapshot --split NAME=GLOB — per-split version ids for stratified datasets (train/val/test). Pure metadata: the top-level version id is unchanged. Drift reports now say which split moved.
• framepin.integrations.to_mlflow(run) / to_wandb(run) — tag the active MLflow/W&B run with the pinned dataset version ids. Lazy imports; framepin stays zero-dependency.

79 tests, Python ≥3.9, no dependencies. pip install framepin
