/**
 * Configuration Module — legacy-key normalization, defaults merge, and explicit
 * on-disk migration. Pure normalization primitives consumed by config-loader.cjs
 * and config-schema.cjs. `loadConfig` was extracted to config-loader.cjs per
 * ADR-857 phase 2e (#885) and removed from this module per #893.
 *
 * ADR-457 build-at-publish: the hand-written bin/lib/configuration.cjs collapsed
 * to a TypeScript source of truth. Behaviour is preserved byte-for-behaviour
 * from the prior hand-written .cjs; only types are added.
