feat: cloudflare pages deploy config

* wrangler.toml — Pages project "nesy-solver", pages_build_output_dir=dist
* public/app.js — switch /api/strategy?class=X to /api/strategy/X path form
  to match the V backend's /strategy/:class route
* .gitignore — ignore dist/ (Pages build output) + .wrangler/ + node_modules/

Deploy (after `wrangler login`):
  mkdir -p dist && cp index.html dist/ && cp -r public dist/
  cp deploy/_redirects dist/_redirects
  wrangler pages deploy dist --project-name=nesy-solver

_redirects proxies /api/* to https://nesy-solver-api.fly.dev so the frontend
stays portable — backend URL can change without frontend changes.
