Module prune 

Purpose: Facade for done-queue pruning surfaces.

Responsibilities:

• Declare focused prune companion modules.
• Re-export the stable prune API used by queue callers.
• Keep prune regression coverage colocated with the prune module.

Scope:

• Thin module root only; prune types and behavior live in sibling companions.

Usage:

• Used through crate::queue::{PruneOptions, PruneReport, prune_done_tasks}.
• Crate-internal helpers remain available through crate::queue::prune::* re-exports.

Invariants/Assumptions:

• Re-exports preserve existing caller imports.
• Core prune behavior remains unchanged while implementation is split across companions.
