test: register wave-3 carves (qa, browse, retro) — guards, touchfiles, pins, baselines

CARVE_GUARDS gains the three entries; qa's monolith invariant retires.
auq-format carve-safety now keys on the skeleton+sections union shipping
the AUQ block (first tier-1 carve: browse never renders it by design).
Baselines: parity v1.69.1.0 at 18 sectioned skills; ratchet recaptured.
