fix(rules): CHOICE-007 detect passive & long-parenthetical class-action waivers (v1.2.0)

v1.1.0 matched only the noun "class action waiver" or an active "waive …
class action" with the object within 40 chars of the verb. It missed the
passive "the right to a class action is hereby waived" and the boilerplate
"waives, to the fullest extent permitted by law, any right to bring or
participate in a class action" (the long parenthetical pushed the object past
40 chars). Widen the active window to a sentence-bounded 100 chars and add a
passive branch tempered so a negated "class action is NOT waived" cannot
match — the rule's inline-negation guard only inspects text before the match,
not a negation between "class action" and "waived". Mirrors the CHOICE-008
v1.2.0 jury-waiver fix; the consumer-heading gate is unchanged.

Probe: 5 fire cases (noun + active + passive + long-parenthetical + expressly-
waived), 4 silent cases (do-not-waive, nothing-herein, no-waiver, passive-not-
waived) plus the non-consumer-scope guard. Finding-delta over the contracts
corpus and all golden tiers: zero fired-flips, zero finding-count changes.
