"""Tests for _catalog_has_provider() with compound provider IDs.

Compound provider IDs like "custom:zenmux-relay" or "custom:glm-free-relay"
normalize to "custom" via _normalize_provider_id(). The existing three
clauses in _catalog_has_provider() already handle these correctly:

  C1: exact raw match  ("custom:zenmux-relay" ∈ raw_ids)
  C2: normalized ∈ raw_ids  ("custom" ∈ raw_ids)
  C3: normalized ∈ norm_ids ("custom" ∈ norm_ids)

This test guards against regressions and verifies that no 4th clause is
needed for compound IDs.
