Simplify ScaNN post: analogy-driven, engineering-accessible rewrite

Replace math-heavy sections with concrete analogies throughout:
library sections for partitioning, restaurant compression for AVQ,
spy thriller filing for SOAR, artist follow filter for pre-filtering.
Keeps technical accuracy but leads with intuition at every step.
