De-clone the STRUCTURE: six new form arcs + six new progressions (REPERTOIRE wave 3)

The census said form "pop" = 128/240 — half the catalog walked one 8-node arc — and minor_run/deep_two carried 79/67 of 28 progressions. This adds six genuinely different dramatic shapes as FORMS data (same Tok vocabulary, same buildForm walker, names chosen to classify correctly under csd-engine…

NEW ARCS — aaba head / head 2 / bridge / head 3 / coda — the 32-bar song form; SOLO_IDIOM splices head->bridge->SOLO->head out (jazz, bebop) vamp groove / layer in / cook / peak vamp / breakdown / layer out / outro

NEW PROGRESSIONS — whole_tone (aug planing), interchange (I-bVII-IV-iv), mediant (I-III-I-bVI), blues_16 (Watermelon Man vein — 128-beat cycles, fast genres only), quartal (sus4 planing), epic_maj (I-V-IV-V — authors' wishlist).

REASSIGNED — pop 128->88 (-40), dj 40->37, wave 39->35; vamp 10, aaba 13, duet 7, throughline 6, suite 5, storm 4.

• MEASURED, retuned by assignment (never the fence): first pass 224/240 — the losers were tight-auto-target invented genres (7 reverted to pop) and knife-edge progression hosts (7 additions dropped/re-homed)
