Give the finish reviewer and documenter craft-floor authority

Codex's own post-mortem of the second hamster-wheel session: it loaded
the kicker ban, shipped five kickers anyway, and then the reviewer and
documenter 'compounded it by accepting, and even canonizing, the
invented label style'. Nothing downstream of the builder ever re-read
the floor.

The reviewer gains check 6, Floor: read craft-floor.md (now the one
skill reference it may read, passed in its inputs) and hold the
screenshots against the Refuse list; a banned element is a material fix
even when it matches nothing in the comp, because fidelity cannot
authorize what the floor refuses. The documenter gains the mirror rule:
a floor refusal lands in its not-canonized line as a carried defect,
never in DESIGN.md as a rule future surfaces inherit.

Also updates the live-reference contract test to match the applier's
condensed no-server sentence, which still carries the same guarantee.

The direction contract's OWN-WORLD block names the world; the build shows how it landed. Where they diverge, the build wins and the prose may note the divergence.

+5. Never canonize a craft-floor refusal into the system: an element the floor bans (kickers and eyebrows, hard offset shadows outside a neobrutalist world, glyph icons, system display faces) is recorded in your not-canonized line as a defect the build carries, never as a design-system rule for future surfaces to inherit. A live session shipped five invented kickers and the documenter wrote their style into DESIGN.md; that is how one violation becomes the house style.
