kb: add country/folk guitar pack

5 progressions (8-bar country I-IV-V, Wagon Wheel folk axis, ragtime I-VI7-II7-V7 circle, Rising Sun 6/8 climb with corrected changes, bluegrass I-IV-I-V) x 2 plays: open G/C-family boom-chick sets with capo strategy, anchor-finger folk grips, barre fallbacks. Comping documents boom-chick, Carter bass runs, Travis picking, train beat, waltz. Sourced Lester Flatt G-run licks. Research corrections honoured (Rising Sun is i-III-IV-VI, not Andalusian; ragtime is the full VI7 circle). Validator and build green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
