Summary:

This diff introduces a new BaselineImprovementAnalysis healthcheck that evaluates whether an optimization experiment has improved over a baseline arm.

Key features:

- Compares best performing arms against a baseline arm for each objective metric
- Supports both single-objective and multi-objective optimization

Status logic:
Pass: All objectives improved over baseline
Warning: Some objectives improved over baseline
Fail: No objectives improved over baseline

This analysis -
- Automatically selects baseline (explicit → status quo → first trial) or accepts user-provided baseline
- Supports customization via documentation_link and no_improvement_message parameters
- Returns a HealthcheckAnalysisCard with detailed per-metric breakdown

The healthcheck is integrated into the ExperimentAnalysisOverview to run automatically as part of the standard analysis suite.
