QSG-2D-1M Phase 1 — per-sync render statistics for the 2D mesh / results QSG renderers.

A Qsg2DRenderStats value is filled in during one updatePaintNode() sync (dirty reasons, visible element counts, per-pass built-vertex and uploaded-byte counters, timings) and emitted as a single log line when runtime perf logging is enabled:

 OPENSWMM_RENDER_PERF=1

Logging is silent (and the formatting path is never entered) unless the environment variable is set, so shipping builds pay only a cached bool check per sync.

The struct is deliberately Qt-Core-only (no Qt Quick / Gui types) so it can be unit-tested headlessly — see tests/unit/test_qsg2d_renderstats.cpp.
