transformerless_lm: v59 results (iambic + threading)

Mean creativity 0.6147, peak 0.6176. Monotone climb across cycles 1-4
(0.610 -> 0.617). Less peaky than v55 but more consistent. Pulled
sequential Richard II lines ("scepter'd isle" + "earth of") plus
Coriolanus/Taming characters (menenius, bianca, katharina, sicinius,
leontes). Confirms language primitive (iambic) shifts substrate from
"lucky peaks" to "consistent growth".
