host 172accb2ec feat(chv): hybrid executor core — routing, clean pool, data disk, snapshot tenant check
Track A (§9.1 items 1-4, DESIGN-HYBRID.md):
- dispatch_task_hybrid: route by tier + lease state (resident resume/cold
  vs pool hit/cold/queue, 300s queue timeout -> host_capacity_exceeded)
- clean pool prewarm split from prewarm_persistent_vm: tenant-less birth
  (no data disk, no seed, no Gitea sync wait), binding deferred to
  acquire; warm_pool_sync_incomplete fail-closed at allocation
- tenant data disk mount at acquire (attach_tenant_data_disk, PUT
  /vm.add-disk + chv-data-mount) and unmount+sync at release;
  _verify_task_disk_source invariant: task disk must be the tenant's
  data disk, never the clean snapshot disk
- restore_vm validates tenant_id before restore: unregistered/unmarked
  snapshot denied in strict (hybrid) mode, mismatch -> snapshot_tenant_
  mismatch fail-closed, audit vm_restore_denied (host_id + tenant only)
- settled values: 2 warm per host, pool cap 50% of low-freq peak,
  resident cap 50% of VM slots, 1 snapshot per tenant per 30 days
