docs(simulation): sweep the last pre-I1 floor-framing comment (Tyre's non-blocking follow-up)

DISTRICT_MIN_WL_M's doc in window_derivation_golden.rs still carried
the 'NOT 2×DISTRICT_M by coincidence alone' framing the I1 fix
inverted everywhere else — now states the rung authors the floor and
the terrain-octave coincidence is guard-pinned, matching the rewritten
MIN_WL_BANDS_M and coast_invention docs.
