feat(rts): extend Reference Transition Scenarios to multi-regulation (CRA + MaschinenVO)

Roadmap item 2: the RTS now pin MaschinenVO + convergence Expected Outcomes, so the
convergence USP is a living regression, not just a one-off section.

- RTS-003 (machine + ISMS, networked): full multi-regulation archetype — maschinenvo
  expected_delta + convergence expected_multi_target (links TP-ISO27001-CRA-MaschinenVO-v1).
  Generator runs the convergence pattern through RS-005: 4/4 machine-safety delta MISSING +
  4/4 expected multi-target caps converge. PASS.
- RTS-001 (component): MaschinenVO modeled as `uncertain` (a pure component is usually not a
  machine; deciding question is_safety_component) — engine must never assert it applies. Honest,
  parallel to the Data-Act handling.
- RTS-002 (machine, QMS-only): MaschinenVO `applies` (is_machine) but LOW convergence — no ISMS
  means the cyber side is entirely delta, so few caps are shared. The honest contrast that the
  convergence USP rewards companies who already run an ISMS.
- generator: per-RTS maschinenvo/convergence Soll-Ist checks; convergence pattern run once and
  reused. Data Act stays `uncertain` everywhere, never asserted.

All 3 RTS PASS. 18 tests (transition+company), mypy --strict clean, check-loc 0.
Non-runtime (knowledge + reference harness) -> no deploy (ADR-001).
