"""Shared fixtures for tests/acp.

Keeps the ACP server tests offline: ``HermesACPAgent._build_model_state``
calls ``hermes_cli.inventory.build_models_payload``, which (without this
fixture) performs live network fetches — models.dev registry, GitHub model
catalog, Copilot token exchange, Anthropic model list — adding ~3s of real
SSL/socket time to every test that creates or loads a session (~147s total
for test_server.py alone).

Tests that assert model-state behavior re-patch these same attributes with
``unittest.mock.patch`` / ``monkeypatch``; inner patches win, so this
default is transparent to them.
