wickworks v0.3.0 — primitives-only purification Breaking: removes divergences + divTrends outputs and the entire signals/ package. Wickworks now emits only raw indicators, SMC structural facts, and summaries. Derived signals (divergence, crossovers, golden/death crosses) are the consumer's job. Includes: - README rewritten with primitives-only contract - schema.json published as release artifact - registry trimmed, signals/ package deleted - tests adjusted for new shape
