Wave 5: execute the bootstrap against real AWS + fix verify script.

- Created S3 bucket acdl-tfstate-581513795199-us-east-1 (versioning
  enabled) + DynamoDB table acdl-outbox (PAY_PER_REQUEST, PK contractId,
  SK eventType#eventTs) via create_state_backend.py.
- Created IAM user acdl-spike-runner + scoped inline policy
  (DenyEverythingElse) + initial key via create_iam_user.py.
- Rotated the spike key via rotate_spike_key.sh: old key deleted, new
  key in gitignored .env.secrets (chmod 600).
- verify_phase08.sh fixes: (a) heredoc python instead of -c to avoid
  bash quoting issues; (b) Check 4 uses the bootstrap root key to
  inspect IAM (the spike key is least-privilege and cannot iam:GetUser
  - that itself confirms the policy denies non-granted actions); (c)
  get_user_policy returns PolicyDocument as a dict, not a URL-encoded
  string in this boto3 version - handle both.
- VERIFIED: caller identity is acdl-spike-runner (not root), S3 + DDB +
  IAM user + Deny-everything-else policy all present, .env.secrets +
  .bootstrap_state.json gitignored.

D-034 closure: user must manually rotate the root key in the AWS IAM
console now (the bootstrap root key has served its one-shot purpose).
