Module startup 

Startup phase coordination primitives.

This module provides the product-neutral mechanics for ordered startup phase execution: duration collection, optional phase failure handling, report aggregation, and shared tracing. Product crates still own concrete initialization work such as migrations, cache creation, driver loading, runtime config reload, audit setup, and application state construction.
