[AZ-589] [AZ-590] Close completeness gate cycle 1: VIO remediation tasks

The Product Implementation Completeness Gate (cycle 1, 2026-05-16)
audited 107 done product tasks. 105 PASS / 0 BLOCKED / 2 FAIL.

FAIL findings — both AZ-332 (OKVIS2) and AZ-333 (VINS-Mono) ship a
real Python facade + AC-tested fake backend, but their native pybind11
bindings (_native/okvis2_binding.cpp, _native/vins_mono_binding.cpp)
are skeletons: _build_estimator() sets estimator_built_ = false; the
first add_frame() raises *FatalException("estimator not yet wired").
Production-default VIO and the comparative-study path both crash on
the first nav-camera frame.

Remediation tasks created in _docs/02_tasks/todo/:
  - AZ-589  remediate_okvis2_threadedkfvio_wiring  (5pt)
  - AZ-590  remediate_vins_mono_estimator_wiring   (5pt)

Both tasks also seed the per-binary bootstrap register_strategy() call
sites — the existing strategy registry in runtime_root/__init__.py is
never invoked in src/ today.

Returning to implement-skill Step 1 to parse Batch 66 against these
remediation tasks (per Step 15 option A).
