merge: hoà cập nhật mới từ origin/feature/delta-team/epic-R04 (R08 Chat UI Hub + R10)

Đồng nghiệp đã push thêm 10 commit lên nhánh trong lúc đang xử lý merge
trước đó (R08-T01..T06 chat_panel.py split, R08 folder/dashboard/graph/
scheduling hoàn thiện, R10 CI Quality Gates + Contributor Recipes + E2E
smoke test). Resolve conflict:

- application/monitoring/__init__.py, domain/tasks/__init__.py,
  infrastructure/persistence/json/__init__.py: chỉ khác docstring — giữ bản
  HEAD (đầy đủ ngữ cảnh EPIC hơn), hợp nhất __all__ khi cần
  (MonitoringQueryService).
- tests/fakes/__init__.py: hợp nhất __getattr__ để lazy-load cả
  FakeToolExecutor lẫn ToolInvocation (bản HEAD thiếu ToolInvocation), bỏ
  entry "FakeClock" bị lặp trong __all__.
- tests/integration/test_routing_surfaces.py (deleted by them): khôi phục
  lại bản đã sửa ở lần merge trước — verify lại: API routing
  (RoutingApplicationService.resolve/_apply_routing/_apply_co4e_routing)
  không đổi sau khi chat_panel.py chuyển sang presentation/chat/*, 9/9 test
  vẫn pass trên code đã merge.

Ghi chú (không sửa, ngoài phạm vi merge): tests/fakes/__init__.py trên nhánh
remote export "ToolInvocation" từ fake_tool_executor.py nhưng class này đã
bị xoá nhầm từ commit chung 10739f1 (breakdown folder tree epic R01) — hiện
là dead code, không ai import, nhưng sẽ raise ImportError nếu có test nào
sau này thử dùng.

Đã chạy pytest tests/: 793 passed (không phát sinh fail mới so với lần
merge trước — 8 fail còn lại đều do môi trường sandbox: thiếu package
keyring, và tên thư mục checkout "cowork-local" thay vì "cowork_local"
khiến vài test spawn-subprocess không import được package).
