First Part II module. The cumulative reference adds a second engine (src/engine/puzzle: grid, lexer, parser) beside Part I's; nouns and properties are data in src/content/words.json, and the engine names only IS/AND/NOT/TEXT and the base rule TEXT IS PUSH. Rules are recompiled from the board on every change; rules() is a sorted set. Adds the M6 scenarios and tests (rows, columns, shared IS, AND distribution, stacked text, base rule), the HOT word as a data-only Expansion Drop, the lesson with the Part II bridge, and the Rust LevelDef shape in harness.md.
