Bumps mlflow from 3.15.1 to 3.16.0.

Release notes

MLflow 3.16.0 includes several major features and improvements

Major New Features

🎨 Custom Trace Views: Design your own trace UI in plain English — describe the view you want and the MLflow Assistant builds it for you, laying out exactly the fields you care about with no config files or custom code. Save, name, and reuse views per experiment so your whole team shares the same lens on your traces.

🔭 Redesigned Trace Experience (now default): The trace explorer has been rebuilt from the ground up and is now the default — tighter row density, cleaner navigation, and a redesigned span-tree view. Reorder columns, add configurable custom columns from any trace tag or metadata field, and find multi-turn conversations inline via session grouping.

🔗 Span Links: Spans rarely stand alone. MLflow 3.16.0 adds first-class span links so relationships between spans — a retrieval step, a tool call, a downstream trace — are captured and navigable. Record links in your SDK and the trace explorer surfaces them in a dedicated Links tab to jump straight to the destination span.
