chore(01-01): scaffold Phaser 4 + React 19 + Vite + TS template + Phase-1 deps + firewall directories

- Built equivalent React + Vite + TypeScript scaffold by hand because the official
  npm create @phaserjs/game@latest scaffolder is interactive-only and the documented
  --template/--yes flags are ignored (verified 2026-05-08 with create-game v1.3.2).
  Plan Step 1 explicitly authorizes this fallback. Resulting tree mirrors the
  official template shape: index.html, src/main.tsx, src/App.tsx, src/PhaserGame.tsx,
  src/game/main.ts, src/game/scenes/Boot.ts.
- Installed Phase-1 production deps at versions verified in RESEARCH.md:
  phaser@4.1.0, react@19.2.6, react-dom@19.2.6, idb@8.0.3, lz-string@1.5.0,
  zod@4.4.3, crc-32@1.2.2, gray-matter@4.0.3, yaml@2.8.4, inkjs@2.4.0.
- Installed Phase-1 dev deps: vite@8.0.11, @vitejs/plugin-react@6.0.1,
  typescript@6.0.3, @types/react@19, @types/react-dom@19, @types/node@22,
  vitest@4.1.5, @vitest/ui, happy-dom, fake-indexeddb@6 (for Plan 03 IDB tests),
  @playwright/test@1.59.1, eslint@9, eslint-plugin-boundaries@6.0.2, inklecate@1.8.1.
- Created the seven architectural-firewall directories under src/ with .gitkeep
  markers (sim, render, ui, save, content, audio, store) — siblings to the
  template-provided src/game/ — so Plan 02's ESLint boundaries rule has clean
  targets per CLAUDE.md 'Architectural Firewall'.
- Created repo-root /content/ (with /dialogue/ and /seasons/ subdirs) and /assets/
  trees per CONTEXT D-11, D-12.
- Pre-declared all downstream-required scripts in package.json so Plans 02–06 only
  edit code, not script keys: dev, build, preview, lint (--max-warnings 0 per
  RESEARCH CI Pitfall C), test (--passWithNoTests=false per CI Pitfall B),
  test:watch, validate:assets, compile:ink (no-op stub for Phase 1; Phase 2
  replaces with real inklecate invocation), ci.
- TypeScript strict mode enforced via tsconfig.json + tsconfig.app.json + tsconfig.node.json.
- npm run build succeeds (tsc -b && vite build) producing dist/index.html and
  dist/assets/index-*.js (~1.5MB Phaser bundle; code-splitting deferred to Phase 2+
  when actual scenes exist).
