fix(core): truepeak UI copy no longer promises a hard ceiling

The registry description and the rack summary said the true peak is never above
the ceiling. The limiter holds a 4x estimate, and full-band noise can land up to
about 1.7 dB above it, as the docs now say. The summary reads "held near", the
description names the estimate and the overshoot, and the rack blurb says "holds
... to a ceiling". No skill file changed, so the skills manifest is unchanged.
