fix(rules): CHOICE-008 detect passive 'jury trial is hereby waived' & long-parenthetical jury waivers (v1.2.0)

v1.1.0 matched only the active form with the object within 40 chars of the
verb, and required "waive" to sit BEFORE "jury trial". It missed two common
forms: the passive "the right to a jury trial is hereby waived", and the
boilerplate "waives, to the fullest extent permitted by law, any right … to a
trial by jury" whose long parenthetical pushed the object past the 40-char
window. Widen the active window to a sentence-bounded 80 chars ([^.] never
crosses a period) and add a passive branch, tempered so a negated "jury trial
is NOT waived" cannot match.

Probe: 5 fire cases (2 baseline + passive x2 + long-parenthetical), 4 silent
cases (do-not-waive, nothing-herein-waives, retains-right, passive-not-waived).
Finding-delta over the contracts corpus and all golden tiers: zero fired-flips,
zero finding-count changes.
