chore(guards): register wave-1 carves; monolith invariants retire; baselines + ratchet follow

CARVE_GUARDS gains review/codex/land-and-deploy (12 carved skills total);
their MONOLITH_INVARIANTS entries retire (invariants now generate from the
registry, cso precedent). Touchfiles: carve-section-loading covers the three
new carves; the codex + land-and-deploy LLM-judge dep lists widen to their
sections. Regen + goldens + branch-internal baseline + ratchet ceilings
recaptured (review 24,052 -> skeleton-based ceiling; union floors hold).
