feat(probe): add third-party dial-test adapter for 15C (tsk_-WC9smQK7YRt)
Implements ProberAgent interface + Alibaba Cloud CloudMonitor Synthetic adapter:
- ProbeTarget / VantageResult types aligned with 15A schema (L3 always nil)
- AliyunSyntheticAgent: CreateSiteMonitor → poll → map to VantageResult
- ISP vantage uses "3rd-{ISP}" prefix; Redis key probe:{node}:CN:{region}:3rd-*
- Degradation: API error/rate-limit/timeout → skip vantage, log + counter (no write)
- RunOnce(ctx, targets) shape for 15H assembly wiring
- Credentials via cfg only (env-var injection, zero hardcoded secrets)
- 6 new tests (mock vendor server): normalization, rate-limit, timeout, Redis keys,
failed-target L1, no-credentials check; all 22 probe-package tests pass
