"""Unit tests for the pure addon drift-discovery core.

The live external test (`tests/external/update/addons/`) is warn-only and
opt-in; the reconciliation logic it relies on is exercised here with fixture
catalogs covering the three behaviours the requirement calls out: a version
bump, a newly discovered addon, and a marketplace entry intentionally ignored
by the curated relevance rules.
