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.
