P1: quality_launcher_apply is now a pure preset -> rows mapping
(psxq::rows_from_runtime plus startup constants); it never writes the live
globals. The in-game menu publishes only thread-safe callbacks: that
mapper, and a re-detect that returns this session's detection (a fresh
probe needs the GL context and mutates the run's state, so it stays in the
pre-game launcher). Summary/reason strings and the detection are fixed on
the main thread at menu setup; settings_get reads only the main-thread
snapshot.
P2: psxq::MenuSelection keeps what the player selected versus what is live.
A pick's next-launch rows and netplay-deferred rows stay selected for the
next seed until the live value matches; other rows follow live. The host
classification moves to psxq::classify_launcher/row_differs (same rules).
Tests: quality_presets_test test_ingame_menu_host_path runs the review's
fixture through the host get/pick/apply/save path (Ultra -> High, then
Antialiasing = NONE; a governed edit is still Custom from High; a netplay-
deferred row stays selected). menu_quality_callbacks_test guards the
draw-thread callbacks against runtime writes and stateful calls.
