Create reusable contract tests for TTS Plugin Architecture: - conftest.py: shared fixtures and stubs (FakeEngine, FakeSession, etc.) - test_types_contract.py: value object contracts (frozen, immutability, equality) - test_errors_contract.py: error hierarchy contracts - test_manifest_contract.py: manifest type contracts - test_engine_contract.py: Engine protocol contracts (lifecycle, dispose) - test_session_contract.py: EngineSession protocol contracts - test_capabilities_contract.py: capability protocol contracts - test_host_context_contract.py: HostContext contracts - test_plugin_contract.py: plugin contract (exports, create_engine) 124 tests covering all public API contracts.

"""Contract tests for HostContext.

These tests verify that HostContext satisfies the architectural requirements:
|
|
- Minimal (3 fields maximum)
|
|
- Frozen dataclass
|
|
- config_dir: Path
|
|
- logger: Logger
|
|
- http_client: HttpClient protocol
