fix(team): repair runtime snapshot caching and rss sampling regressions

Pre-existing regressions из 'cache transcript and telemetry scans':

- pidsMissingUsageStats теперь всегда фильтрует runtimeUsagePids по
  отсутствию stats, а не только когда runtimeProcessRowsForSnapshot
  null. Пустой/неполный results-row больше не блокирует pidusage
  fallback.
- Кэш runtimeProcessTableCache очищается при invalidateRuntime-
  SnapshotCaches и не репопулируется in-flight'ом, который начат до
  invalidate (через generation token + caller-aware cache context).
- runtimeProcessUsageStatsCacheByPid очищается в invalidate, а в
  shared OpenCode host refresh branch'е сбрасывается negative-cache
  для конкретного pid'а перед таргетным sample'ом.

Зеленит 25 теста в TeamProvisioningService > getTeamAgentRuntimeSnapshot,
включая 'uses batched pidusage rss values', 'captures CPU and memory
history', 'does not cache live runtime metadata when invalidated while
the probe is in flight', 'shows RSS for OpenCode secondary lane host
pids'.
