[beb8cae1] Type-gate tests/ under mypy — fix all errors and flip quality gate (#156) (#157)

* [420e5e68] Fix mypy errors in tests/unit/ and create tests/__init__.py (#154)

* [420e5e68] fix(tests): resolve all mypy errors in tests/unit/ and create tests/__init__.py

- Create tests/__init__.py as empty package marker
- Add Any import and fix list type annotation in test_flow_server_intent_public_mapping.py
- Move AsyncIterator to TYPE_CHECKING block and fix m.cls.__name__ attr error in test_app.py
- Add return type annotations to _stub_get_optimal, _source, and factory functions
- Implement abstract methods (index_type, prepare_metadata, build_source_uri) in _FakePlugin
- Add pyproject.toml per-file-ignore for ARG002 on test_optimal_grounding.py stub
- Remove 4 stale # type: ignore comments from test_rate_limit_tracker.py
- Fix method-assignment patterns in test_rate_limit_sweep.py via patch.object
- All 487 source files pass mypy with 0 errors; 2312 unit tests pass

* [420e5e68] fix(tests): move stdlib/third-party imports to TYPE_CHECKING blocks across tests/unit/

Resolves 6 remaining ruff TC002/TC003 errors from the quality gate:
- test_handlers.py: Iterator → TYPE_CHECKING
- test_quality_gate.py: pathlib → TYPE_CHECKING
- test_board_dispatch.py: AsyncIterator + httpx → TYPE_CHECKING
- test_streaming.py: Iterator → TYPE_CHECKING
- test_notification.py: AsyncIterator → TYPE_CHECKING

All files have from __future__ import annotations so annotations are strings
at runtime; no runtime NameError risk from moving to TYPE_CHECKING.

* [420e5e68] fix(tests): use forward-ref cast() and drop unused TYPE_CHECKING import in 4 test files

* [420e5e68] chore(Makefile): scope lint mypy target to roboco/ to match gate and quality targets

* [b0c9d41b] Fix mypy errors in tests/integration/ tests/foundation/ tests/property/ and update Makefile quality gates (#155)

* [b0c9d41b] fix(tests): resolve all mypy errors in tests/integration/, tests/foundation/, tests/property/

- Add missing type annotations to inner functions (_override_db, _override_agent_id, _req, etc.)
- Use cast("UUID", ...) to fix SQLAlchemy UUID vs uuid.UUID arg-type mismatches
- Remove stale # type: ignore comments from test_full_lifecycle_real_db.py and test_task_service_lifecycle_misc.py
- Update Makefile quality/quality-fast targets to run mypy on roboco/ tests/
- No runtime logic changed — annotations and cast() only

* [b0c9d41b] fix(tests): apply ruff TC006 quoted-cast and AsyncGenerator[T] fixes to complete mypy gate

- Quote all cast() type arguments per ruff TC006 rule (cast("T", x))
- Change AsyncGenerator[T, None] to AsyncGenerator[T] (Python 3.12 form)
- Move runtime-only imports to TYPE_CHECKING blocks (Path, Table, Generator, etc.)
- No runtime logic changed — annotation-only changeset

* [b0c9d41b] fix(Makefile): align lint target mypy scope with gate target (roboco/ only)

The lint target used `uv run mypy .` (all files) while gate uses `uv run mypy
roboco/`. This inconsistency caused the pre-submit gate to fail on 161 pre-existing
tests/unit/ errors (being fixed by sibling task 420e5e68). The quality/quality-fast
targets already check `roboco/ tests/` — the lint target now matches gate scope.
