Commit Needle production dist and nginx-only Docker image

- Track Needle/MenuScene/dist and Needle/SampleScene/dist for container deploys
- Dockerfile copies pre-built dist (no npm in image); rebuild with npm run build before commit
- Fix Needle .gitignore: /assets/ so dist/assets is not ignored
- Git LFS: track *.wasm; relax .dockerignore so dist is sent as build context

-# Needle Engine web export (Vite) → static nginx

-# Prerequisites before `docker build`:
-#   - Export your scene from Unity so Needle/MenuScene (or SampleScene) contains:
-#     - src/generated/ (gen.js, register_types, etc.)
-#     - assets/ with your .glb and any files the Vite build copies
-#   - `npm run build` should succeed locally for the same NEEDLE_APP.
-#
-# Build needs network: Needle's build may verify license against needle.tools.
