fix(P5): doc drift — Nova rebrand stale refs in docs/decks/roadmap/arch

v1.15-Nova rebrand doc verification (phase/05-final-review-ship) found
stale ACDL references where the code/terraform already uses Nova names.

Critical drift fixed (doc said old name; code uses new):
- README.md: `.acdl/contract.yml` -> `.nova/contract.yml`;
  `acdl-spike-runner` -> `nova-spike-runner`; ABAC tag keys
  `acdl:owner|contract` -> `nova:owner|contract`.
- docs/environments/index.md: `acdl-contract-ingestor` -> `nova-contract-ingestor`;
  `aws:PrincipalTag/acdl:owner` -> `nova:owner`; `acdl-contracts` -> `nova-contracts`.
- docs/consumer-guide.md: `acdl-change-requests` -> `nova-change-requests`;
  state bucket example `acdl-qa-state` -> `nova-qa-state`.
- docs/presentations/* (4 decks + 2 HTML + talking-points): `acdl:owner|contract|
  environment|cost-center` -> `nova:*`; `ACDL_LIFECYCLE_MODE` -> `NOVA_LIFECYCLE_MODE`.
- pipelines/modules-lifecycle.yml comments: `ACDL_LIFECYCLE_MODE` ->
  `NOVA_LIFECYCLE_MODE` (workflows already use NOVA_; the contract comments were stale).
- docs/NOVA_MIGRATION.md: status banner -> COMPLETE (P5 cutoff passed).
- .ciagent/ARCHITECTURE.md: header `ACDL` -> `Nova`; NOVA_LIFECYCLE_MODE
  rename noted in the live lifecycle-mode section (v1.15 addendum already correct).
- .ciagent/ROADMAP.md: v1.15 phase statuses P1-P4 pending -> complete
  (v1.15.1..v1.15.4); P5 -> in progress (phase/05-final-review-ship).

Verification:
- grep for `acdl:*` tag keys / `.acdl/contract` / `acdl-contract-ingestor` /
  `acdl-contracts` / `ACDL_LIFECYCLE_MODE` in README/docs/pipelines -> 0 hits
  (excluding explicitly-unchanged repo path `acdl/.github/...`,
  `continuous-intelligence/acdl`, and historical narrative).
- core/output_publisher.py uses `/nova`; schemas/tagging-standard.json uses
  `nova:*`; terraform uses `nova-*` (0 `acdl-` in *.tf) — docs now match.
- git tag v1.15.0..v1.15.4 exist.
- pytest tests/test_lifecycle_mode_flag.py tests/test_pipeline_contract.py
  -> 111 passed.
