Resolved 2026-07-08 (cfront-agent) — dup of perf-gtk-system-header-parse, fixed

test-core#602 = test/test_c_gtk.pas (the GTK header test). Not a code regression: it TIMEOUT'd (even serial, 45.4s) purely on the O(n²) C-preprocessor cost, same class as #599/#601. Fixed in d531804e (amortized CPrepOut growth) — GTK2 preprocess 33.7s→6.7s, full compile ~40s→9.8s, well under the unit deadline. --dump-cpp byte-identical, self-host fixedpoint holds, conformance/cjson/lua/quick green. See perf-gtk-system-header-parse.
