Adopt time-dependent Precision-Recall browser rendering

[uriahf]

Extend existing PrecisionRecallV2 consumer architecture to support time-dependent Precision-Recall curves.

Summary of changes:

1. src/rtichoke/_viz_spec_v2.py:
   • Implement _precision_recall_times_v2_spec_from_performance_data to construct canonical v2 specs from time-dependent performance data.
   • Maintain stable evaluation IDs across horizons and assign unique series IDs per evaluation × horizon.
   • Construct population_horizon prevalence reference lines using cutoff-0 AJ event-risk.
2. src/rtichoke/discrimination/precision_recall.py:
   • Add parameter renderer: str = "plotly" to create_precision_recall_curve_times().
   • Preserve default Plotly behavior while supporting "browser" and "rtichoke_viz" renderers. Raise ValueError for "matplotlib".
3. tests/test_time_precision_recall_v2.py:
   • Add unit and browser acceptance tests for time-dependent Precision-Recall specifications, equality-preservation across equal risk populations, renderer dispatch, and horizon selection/switching in headless Chrome.
