Nothing is measured about an unknown GPU, so the fallback no longer assumes
Ultra's extra work (supersampling above the display, title Ultra extras);
Low would drop Smooth motion and the PGXP extras on what is usually capable
new hardware. Medium keeps the display's resolution with dynamic
resolution under it. Covers unnamed renderers, Linux with only an AMD PCI
id, and unnamed nouveau chips. docs/QUALITY_PRESETS.md states plainly that
autodetect is a static heuristic over name, threads and memory with no
benchmark, and that the dynamic systems keep the frame rate.

Owner decision: Ultra on first launch, with dynamic resolution, Smooth
motion from surplus and the adaptive aspect as the live safety net. Apple
silicon, discrete GPUs, unknown GPUs and 8 GB machines now detect as Ultra;
software GL, Steam Deck, mobile, Intel HD/UHD and small AMD iGPUs stay Low,
mid iGPUs Medium; fewer than 4 threads or under 6 GB still caps.

A title may declare [quality.low|medium|high|ultra] tables of [video] keys.
On first launch, and when the hardware fingerprint changes while a preset is
in force, psxrecomp detects the CPU, threads, RAM and GPU (OS facts; a hidden
1x1 GL window reads GL_RENDERER only when a detection is due and the OS did
not name the GPU), picks the matching preset and saves quality_preset,
quality_base, quality_hardware and quality_detected to settings.toml.
- Each preset is the whole game.toml re-parsed with its keys over [video], so
every [video] key works in a preset with its usual validation.
- A preset in force owns its keys: saved settings.toml values for them are
ignored. Custom (the player changed a governed setting in the launcher)
applies the player's values over quality_base and is never overridden;
new hardware under Custom is only reported.
- Launcher: GameInfo.quality_* (offered mask, detected preset, hardware
summary, quality_apply / quality_redetect callbacks) and
Settings.quality_preset/quality_base, behind RECOMP_LAUNCHER_HAS_QUALITY_PRESETS.
- PSX_QUALITY=<preset> for one run, PSX_QUALITY_REDETECT=1.
- Titles without [quality.*] are unchanged.
Rules (quality_tier.c) and the decision are unit-tested in
quality_presets_test; docs/QUALITY_PRESETS.md.
