greatmengqi a934a822df refactor(config): simplify runtime context access in middlewares and tools ...

- title_middleware: drop the _resolve_title_config() try/except wrapper and the
  optional title_config=None fallback on every helper. after_model/aafter_model
  read runtime.context.app_config.title directly; helpers take TitleConfig as a
  required parameter. Matches the typed Runtime[DeerFlowContext] signature.
- memory_middleware: drop resolve_context() call; use runtime.context directly
  since the type is already declared.
- sandbox/tools.py: drop three layers of try/except Exception around
  resolve_context(runtime).app_config.sandbox. If the config can't be resolved
  that's a real bug that should surface, not be swallowed with a default.
- task_tool.py: same — drop the try/except around resolve_context().
- client.py: drop the set_override() call in __init__ and _reload_config().
  It was leaking overrides across test boundaries and the leak-free path
  (init() alone) is enough for the single-Client case.
- conftest: autouse fixture that initializes a minimal AppConfig for every
  test so AppConfig.current() doesn't try to auto-load config.yaml.
- test_title_middleware_core_logic: pass TitleConfig explicitly to helpers
  instead of patching AppConfig.current globally.
