Changes

• Integrate PreTab 1.0 with configurable preprocessing representations and persisted preprocessing metadata.
• Fix estimator state, refitting, weight continuation, training configuration, monitoring, and HPO behavior.
• Correct metric routing and aggregation, including string-label support in Accuracy and F1.
• Improve model persistence, CPU loading, and retrieval-model save/load behavior.
• Update dependency security requirements, release validation, documentation, and examples.

Compatibility

• Python 3.11–3.13 is supported; Python 3.10 users must remain on 2.0.x.
• Native retrieval dependencies require the tabr extra. Native TabR remains unsupported on macOS arm64.
• Historical 2.0 PLE artifacts require their original dependency environment.
