Adds Snake 404 to the Pages group, next to Dithered 404.

• "404" is drawn as a dot-matrix grid, and every dot is a food pellet.
• A Nokia-style snake slides in and finds the nearest pellet on its own, avoiding walls and its own body.
• It opens its mouth when food is just ahead. Each meal shows as a bulge that stays put while the body slides past, and the snake grows when the tail reaches it.
• When the snake clears the glyph, the digits pop back and it keeps going.
• To play, click the field, then steer with the arrow keys or WASD, or swipe. Hitting a wall or itself makes the snake blink, then autopilot starts again. Esc or moving focus away hands control back.
• Props: code (any digits, e.g. "500"), color, cellSize, speed, maxLength, grid, lcd (Nokia green screen), playable, score, smooth, theme, plus onEat, onClear and onPlayChange.
• Respects reduced motion (the snake stays parked until you play) and pauses while scrolled out of view.
• Includes the docs page with a live demo, entries in the README, the docs index and the skill files, the OG image, and the published registry JSON.

Checked with pnpm test (149 passing), pnpm typecheck, pnpm lint, and screenshots in light, dark and LCD. Frame timing: 361 frames in 6 s, slowest 16.8 ms, none dropped.
