Overview

kohagi's one-line run summary from stderr, parsed into a value object:

kohagi: model=cl-nagoya/ruri-v3-130m dim=512 in=2141 out=2141 skipped=0 truncated=3

SummaryLine.parse returns an instance, or nil when stderr carries no such line, so the caller can fall back to values it computed from the stream. A field the line omits (an older kohagi has no truncated) reads as nil. Knowing kohagi's stderr text format lives here, not in the Summary data.
