Spark factory documentation (hub)

Engineer map for the Spark / SparkLang SPARK_BC factory on sparklang.dev. Does not reimplement SGD, attention, or serve APIs — links code + makefile targets. Eval and train scores are measurement only, not marketing wins.

Reproduction story: SPARK_BC Builder. Diagrams: Diagrams — tool map, shadows, LLM assist vs deterministic SoT. AI model aspects: Model aspects — behaviors, ears/STT, eyes/vision, speaking/TTS, thinking, memory, tools, train, eval, serve. AI knowledge hive: Knowledge — engineer-grade field explainers (transformers → safety) with original diagrams.
