[autodev] Step 13 partial: arch + module-layout cycle-1 sync

Item 1 of the deferred Step 13 refresh set per
_docs/02_document/ripple_log_cycle1.md.

architecture.md:
- Components C1: KltRansac is the cycle-1 operational default while
  AZ-332/AZ-333 are BLOCKED awaiting Tier-2 prerequisites; ADR-001 /
  ADR-002 unchanged (the seam holds; the selection shifted).
- Principle #3: same KltRansac note (cross-link to Components).
- § Technology Stack: OpenCV pin row reflects the cycle-1 relaxation
  to >=4.11.0.86,<4.12 with the leftover-file pointer; OKVIS2 + VINS-
  Mono rows note BLOCKED with AZ-592 / AZ-593 follow-ups.
- § NFR: Dependency CVE pinning row notes the relaxation and the
  CVE-2025-53644 re-validation owed before close.
- § ADR-001: cycle-1 operational note (KltRansac default; AZ-332/333
  facade-only; AZ-589/590 closed Won't-Fix).
- § ADR-009: new Cycle-1 implementation subsection covers
  _STRATEGY_REGISTRY + register_strategy (AZ-591) and the
  pre_constructed kwarg + build_pre_constructed (AZ-618 umbrella;
  Phases A-F including AZ-625 / AZ-687).

module-layout.md:
- shared/runtime_root entry: package layout (was single file in the
  Plan-era sketch); new public-surface table covering __init__.py,
  airborne_bootstrap.py, _replay_branch.py, and the per-component
  factory modules; ownership rows extended (AZ-591, AZ-618, AZ-625,
  AZ-687).

system-flows.md: intentionally not modified — F2 / F8 narratives are
at the component-flow abstraction level and do not reference
compose_root / pre_constructed mechanics, so they have not drifted.

Items 2-4 of the ripple-log refresh set (C1 description, the other
13 components, 8 helpers, tests/*.md) remain deferred to subsequent
sessions.

State: Step 13 stays in_progress; sub_step advanced to phase 6
(component-doc-updates).
