Adds scripts/visual-parity.sh (`just visual-parity`): launches the installed Ghostty 1.3.1 and the Rust build in an isolated headless nested weston (GL renderer, Mesa forced, weston-screenshooter via --debug), with identical isolated config, a deterministic test page (ASCII, ligatures, all SGR styles and underline kinds, 16/256/truecolor, box/block/braille/powerline/nerd icons, CJK, emoji, wide chars, cursor) and a tabs+splits scenario driven through Xwayland, then diffs the captures (terminal area and chrome separately, heatmaps). Fixes found by comparing against the original: - A pane stayed blank after a nested split: the GTK render path called draw_frame(false) where Ghostty uses drawFrame(true) (a re-realized GLArea has a new swap chain that nothing else redraws). - Sprite glyph antialiasing now ports z2d's default 4x4 multisample rasterizer instead of tiny-skia's analytic coverage (pixels differing from Ghostty's reference sprite sheets: 5.76% -> 1.20%, none off by more than 96 levels); the sheet test tolerance is tightened to 0.1%. Result vs Ghostty 1.3.1: test page 0.020% of pixels differ (196 px at curly-underline ends and diagonal box strokes, max delta 86 levels); tabs+splits and headerbar/tab bar are bit-identical. Details in docs/rewrite/notes/visual-parity-VP.md. Test Plan: - just visual-parity (needs weston, weston-screenshooter, xdotool) - cargo test -p ghostty-font (sprite sheet comparison)
