Live validation found two real bugs:
- YunkeClient sent 'source: yunkepc' on every request; msg/chats binds
source as Integer -> 500. Removed (cookie auth suffices, per Phase 0).
- WeChat message talker_id used the masked 'talker' field; the timeline
joins on the full peer id. Now: 1:1 -> oriTalker (full), group -> talker
(member). ori_talker keeps the raw oriTalker (peer/chatroom).

Centralize scraping stealth in YunkeClient.request() so automated traffic
resembles the normal CRM web app and is paced conservatively to avoid
triggering 云客 risk control (pulls M6 rate-limit work forward):
- app/config.py: add 6 tunable settings with conservative defaults
(request_min_interval=1.0, request_jitter=0.8, max_requests_per_run=0,
risk_backoff_{base=2.0, max=60.0, attempts=4}).
- app/scraper/base.py: RateLimiter gains optional jitter + a new wait()
method (fixed min+jitter per-call sleep); gap-based acquire() is unchanged
for backward compat (default jitter=0.0).
- app/session/yunke_client.py: every request now carries browser-identical
headers (UA/sec-ch-ua/accept/accept-language/referer) merged with the auth
headers (per-request overrides win); awaits the shared jittered limiter
before sending; enforces a per-run request cap (RequestCapReached); and
backs off exponentially on risk signals (HTTP 429 or 200 body carrying
频繁/风控/限制/稍后), distinct from the existing 401 relogin-once path.
- tests/conftest.py: zero the throttle env in the test suite so the
conservative prod defaults don't slow unit tests.
- tests/test_yunke_client_stealth.py: 9 new tests (browser headers,
override, limiter spy, 429 backoff, 200-marker backoff, persistent-429
raise, volume cap, unlimited, 401-relogin preserved). TDD red->green.
Suite: 171 -> 181 passing. ruff clean.
