Overview

ucode audit compare LEFT RIGHT — diff two audits.

Each of LEFT and RIGHT can be:

- A path to a font file (audited on-the-fly with
{Audit::FaceAuditor}).
- A path to a face audit directory — its `index.json` is
read for the precomputed report shape.
- A path to a saved `index.json` file directly.

Note: reading from disk only recovers the derived overview shape from Emitter::IndexEmitter, not a full AuditReport. The compare therefore uses the field subset that the overview shape preserves (identity + coverage totals). For a full-feature diff, audit both inputs fresh from their font paths.
