Migrate from Deno/JSR to npm publishing

- @sveltejs/package builds dist/ for @eeeooolll/graphiql with three entry
  points (./, ./component, ./splitter)
- Vitest + svelte-check replace Deno test/check; runes shim no longer
  needed since the Svelte plugin compiles .svelte.ts at runtime
- Drop $app/environment dep in Editor.svelte to support non-SvelteKit
  consumers
- Refactor TabBar tab element from nested <button> to role=tab <div> per
  PLAN.md gotcha; svelte-check flagged the invalid HTML
- README now documents npm install, integration patterns for Yoga,
  Apollo, graphql-modules, Hono/Bun/Deno, plus APQ + keyboard table
