feat: add adaptive polling scheduler infrastructure (Phase 2 Tasks 1-3)
Implements adaptive scheduling foundation for Phase 2:
- Poll cycle metrics: duration, staleness, queue depth, in-flight counters
- Adaptive scheduler with pluggable staleness/interval/enqueue interfaces
- Config support: ADAPTIVE_POLLING_ENABLED flag + min/max/base intervals
- Feature flag defaults to disabled for safe rollout
- Scheduler wiring into Monitor with conditional instantiation
Tasks 1-3 of 10 complete. Ready for staleness tracker implementation.
