perf(signal_v2): raise stock_client TTL for NAS load relief (SP-A1)
...
portfolio 60s → 180s (3분 폴링 → 3회당 1회 fetch)
news-sent 300s → 600s (sentiment는 자주 안 바뀜)
screener 60s → 300s (Top-20 분 단위 변화 미미)
V2 재시작 시점부터 NAS stock에 대한 인바운드 호출이
분당 12 → 분당 3~4 로 감소 예상. 캐시 hit ratio 0~50% → 66~80%.
회귀 테스트 3건 추가로 미래 의도치 않은 TTL 변경 차단.
Also update test_stock_client.py fake_time assertions from 61.0 → 181.0
to match the new 180s portfolio TTL (tests were TTL-dependent).

fix(signal_v2): await cancelled poll_task + public cache_size
...
Code review fixes:
- main.py lifespan: await poll_task after cancel() to avoid client
close racing with mid-fetch task (CRITICAL).
- stock_client: add public cache_size() method; main.py /health uses
it instead of private _cache attribute (IMPORTANT).
19 tests still pass. Deferred to Phase 7 backlog:
- _ctx singleton test isolation (importlib.reload provides isolation in practice)
- poll_loop interval floor (interval >= 60 by design)
- shutdown logging
- response schema validation

refactor(signal_v2): narrow stock_client exception catch + remove dead code
...
Code quality review fixes:
- _cached_request: catch httpx.HTTPError instead of bare Exception
(avoid swallowing KeyboardInterrupt / asyncio.CancelledError)
- _request_with_retry: remove unused last_exc variable + dead post-loop
raise paths. Final sentinel raise preserved for mypy.
6 tests still pass. Deferred to Phase 7 backlog: cache concurrency
coalescing + __aenter__/__aexit__ context manager support.

feat(signal_v2): stock_client + 6 integration tests
...
httpx async client with custom retry loop (max 3, exponential 1s/2s/4s),
memory dict cache (portfolio 60s / news-sentiment 300s / screener 60s),
X-WebAI-Key auth header injection. Stale fallback returns last
successful response with logger.warning on persistent failures.
6 integration tests pass with respx httpx mock.
