Overview

Thin I/O wrapper around mutool trace <pdf> <page>.

Runs mutool on the given pages, captures the XML output, delegates parsing to TraceParser, and returns a flat Array<TraceGlyph> across all pages.

The only class in the trace pipeline that touches the filesystem / spawns subprocesses. Everything upstream (parser, correlator) is pure.
