rcourtman 2636ba9137 test: add comprehensive integration test harness for adaptive polling (Phase 2 Task 9c) 
Add PollExecutor seam and integration test infrastructure:

**PollExecutor Interface:**
- Add pluggable executor interface for testability
- Implement realExecutor wrapping existing poll functions
- Add SetExecutor() for test injection
- Zero impact on production behavior

**Integration Test Harness:**
- Build-tagged integration tests (go:build integration)
- Synthetic workload generator with configurable scenarios
- Fake executor simulating latencies, failures, recovery
- Runtime metrics collection (queue depth, staleness, goroutines)

**Comprehensive Assertions:**
- Queue depth bounds: stays within 1.5× instance count
- Staleness: healthy instances <20s, multiple poll cycles
- Circuit breakers: transient failures recover, permanent stay blocked
- Dead-letter queue: only permanent failures routed
- Scheduler health: snapshot consistency validation

**Test Scenarios:**
- 10 healthy PVE instances (rapid polling)
- 1 transient failure instance (fail → recover)
- 1 permanent failure instance (DLQ routing)
- 55s test duration with 3s base intervals
- Validates full adaptive scheduler lifecycle

Runs with: go test -tags=integration ./internal/monitoring -run TestAdaptiveSchedulerIntegration
