Module preflight 

Preflight summary computation helpers.

The routines in this module gather package metadata, estimate download and install deltas, and derive risk heuristics used to populate the preflight modal. All command execution is abstracted behind CommandRunner so the logic can be exercised in isolation.

Enums
