Product-led-growth (PLG) readiness score API

Transparent weighted PLG-readiness rubric (0-100) over five 0-1 factors with explicit weights — timeToValue 0.25, selfServeConversion 0.25, activationRate 0.20, virality 0.15, expansionMotion 0.15 — returning a rating bucket (plg-ready/capable/needs-work/sales-led) and per-factor contribution breakdown. Answers 'am I ready for product-led growth','what is my PLG readiness','which PLG lever is weakest'.
