Promotes develop to main for the 0.1.0a3 pre-alpha.

What changes since 0.1.0a2

• LoadedBundle.predict_record(record) returns one OutputPrediction per model output: labels, probabilities, the native model's own class decision as predicted_label, or the value for a regressor.
• LoadedBundle.row_from_record(record) returns the validated row in feature order without predicting.
• Record keys follow the schema mapping: the feature name when the model exposes names, the 0-based position otherwise. Numeric strings and true/false are accepted; None only for a feature the schema marks as not required. Errors name the key and never echo the value.
• series fields are written with columns, the shape MLForm consumes.
• EnvironmentMismatchError names the declared and installed scikit-learn versions when a skops-backed bundle fails to load under a different version.
• InvalidManifestError names the writer and reader versions when the manifest comes from another pre-release.

Compatibility

Bundles written by 0.1.0a2 remain valid. schema_version stays "2"; only the series shape changed, and no existing bundle contains one. Format 1 is not frozen.

Verification

• CI on develop for feat: own runtime record predictions in mlbundle #20: lint, types, build, wheel tests on Ubuntu and Windows.
• Local: 1,772 tests, 91.96% coverage; twine check --strict passes for both artifacts.
• Real models: the owner's five 0.1.0a2 bundles load, and record prediction matches the original models' probabilities and class decisions on 302 rows each.
