Keeps both lines: master's PGXP session, draw-distance clamps, masked rejects and saturated-winding NCLIP; the release's render-pass kit additions, verified media/disc extents, timeline/present rings, cull-scale sites. Overlay ABI v30. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

/*

* First-call capture / later-call restore for the scalar host settings a
|
|
* trusted plugin's psx_mod_* setters can change and no launcher control owns
|
|
* (vsync, frame interpolation and its rate, automatic FMV skipping, and the
|
|
* frame periods native VBlank pacing overrides). reset_mod_owned_presentation()
|
|
* in main.cpp runs this at every session start; it lives here so a unit test
|
|
* (runtime/tests/test_mod_session_baseline.c) drives the same code.
|
|
*
|
|
* The first call records the live values -- settings.toml, environment
|
|
* overrides such as PSX_VSYNC, and the launcher are resolved by then -- and
|
|
* writes nothing back, so the first session keeps exactly what the player
|
|
* configured. Later calls write that record back over the live values.
