Verify Hash Chain Integrity

# Verify complete thread hash chain
query {
  verifyThreadIntegrity(threadId: "thread-123") {
    verified
    totalEvents
    brokenAt
    error
  }
}

# Verify specific step
query {
  verifyStepIntegrity(
    threadId: "thread-123"
    stepName: "order_placed"
    idempotencyKey: "order_456"
  ) {
    verified
    hash
    prevHash
  }
}

# Get hash chain data
query {
  thread(id: "thread-123") {
    lastHash
    steps {
      stepName
      hash
      prevHash
      verified
