kb: add reggae guitar pack

5 progressions (circular I-IV-V, two-chord vamp, i-bVII minor vamp,
No Woman No Cry I-V6-vi-IV, verified rocksteady I-ii-iii-ii) x 2
plays: top-3 skank triads, Wailers middle-string set, top-4 partials,
quality-neutral 5+R dyads. One-drop/double-skank/ska/bubble grids
documented. Research flags honoured (NWNC is major-key; Get Up Stand
Up stored as near-one-chord; doo-wop claim replaced with verified
Queen Majesty changes). Validator and build green.
