Documentation-consistency release, no behavior changes: README now covers the full 1.0 surface (temporal/grouped CV incl. explicit folds, operating-point objectives, missing= policies, checkpoint/resume + estimate_cost, MLflow flavor, multi-scale ensembles); API-reference signature blocks and parameter tables are programmatically verified against the real signatures; the cv docs document the explicit-folds form and the automatic groups upgrade; added the Production/Stable trove classifier. Every python block in README and DOCUMENTATION executes as written.
