Extends InputState/InputController with heldDirection (Arrow keys/WASD) and pointerX (follow-the-pointer drag) so games beyond the single-button dino-runner jump are possible. Extracts mulberry32 and the AABB collision check into src/games/shared/ for reuse. Adds orbit-dodger: dodge falling obstacles by moving the ship left/right, original chevron-ship and faceted-gem art. Wires ?game=orbit-dodger into all four example apps and documents the new game/InputState fields in the README.

Summary
orbit-dodger: dodge obstacles falling from the top by moving the ship left/right, original chevron-ship + faceted-gem art (distinct from dino-runner's visual language).InputState/InputControllerwithheldDirection(Arrow keys / WASD, held) andpointerX("follow the pointer" drag/touch, canvas-local logical pixels) — purely additive,dino-runneris unaffected.mulberry32and the generic AABBintersects()check intosrc/games/shared/so both games reuse the same PRNG/collision primitives instead of duplicating them.?game=orbit-dodgerinto all four example apps (vanilla, react-vite, nextjs, angular) so both games are reachable without extra setup.InputStatefields in the README.Test plan
npm test— 135/135 passing (30 new: shared rng/collision, orbit-dodger movement/fallers/collision/index, extendedInputControllerpointer/keyboard tests).npm run lint— clean.npm run build— core/react/angular entries all build.npm run size— core bundle 6.86 KB gzip (was 5.72 KB before this change), well under the 15 KB budget.?game=orbit-dodgermounts the canvas with no console errors inexamples/vanilla. Pixel-level visual verification wasn't possible in this environment (the preview browser pane doesn't actively composite frames, sorequestAnimationFrameis paused) — relying on the automated test suite (including a "render doesn't throw" test) for render-path coverage instead.
