Adds the DuckStation-style widescreen hack as a config option, implemented in the runtime (no regen needed): - gte.cpp: gte_set_display_aspect(num, den). RTPS/RTPT scale the IR1*h/sz screen-X term by (4*den)/(3*num) around the game's own OFX projection centre (identity at 4:3). Games cull against the SXY values they read back from us, so post-projection screen- bounds culls stay aligned with the visible frame. - present: GL letterbox_rect generalised to the configured aspect (gl_renderer_set_display_aspect); SDL_Renderer path gets an aspect-derived logical size + dst rect. Window opens at the configured aspect (clamp_window_4x3 -> clamp_window_aspect). - config: [video] aspect_ratio = W:H (4:3 default, 16:9, up to 32:9) in game.toml, settings.toml (load+save), launcher seed. World geometry keeps correct proportions on the stretched present; screen-space 2D (HUD, FMV, sprite quad widths) stretches — the known limitation of the squash tier. EXPERIMENTAL.
