Adds IS NOT to the Part II parser and a resolution pass (negation, then
identity lock) that turns parsed rules into the rules in force; harness
gains activeRules() and hasProperty(). A leading NOT now breaks the
sentence instead of being ignored (carried from M6 review). Nouns say
which objects they name ("selects"), so the ALL Expansion Drop is one
line of data. Corrects lesson 06's NOT wording; harness.md M7 details.

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.
