v0.13: 性能重构+数值平衡+字体资源落地

性能（调研 7-A 落地）:
- 新增 AnimatedNumber 组件（useRef + rAF lerp，60fps 平滑过渡，不触发 React re-render）
- CrystalOrb 拆 OrbStats 子组件：主体（Canvas+button）不再每 tick 重渲染
  crystals/crystalCap/crystalsPerSec 订阅下沉到 OrbStats，用 AnimatedNumber 平滑
- page.tsx StatsPanel: shallow → useShallow（修复 zustand v5 getSnapshot 崩溃）

数值平衡（调研 7-A 落地，防速通）:
- 新增 src/lib/game/softcap.ts：applySoftcap/applyCostSoftcap/effectiveDecodedForPrestige
- 飞升蓝图公式改 sqrt softcap（阈值 40，power 0.5）
  前 2 蓝图照常给（新手友好），3-6 蓝图需更多解码（防速通）
  - totalDecoded=40 → 2 蓝图（与旧一致）
  - totalDecoded=80 → 2 蓝图（旧=4）
  - totalDecoded=360 → 6 蓝图（封顶）

非商用资源落地（调研 7-B）:
- 安装 @fontsource/share-tech-mono + @fontsource/vt323（SIL OFL 自托管）
- globals.css 加 --font-tech / --font-terminal 变量
- ResourceBar 数值用 font-tech（Share Tech Mono 星舰仪表盘感）
- ArchaeoLogTicker 文本用 font-terminal（VT323 终端绿字）+ GiScrollUnfurled 图标
- 安装 react-icons，引入 game-icons.net 子集（MIT）

交互优化:
- ExpeditionPanel 加探险目的说明（3 资源卡片）+ 节点类型图例（issue #3 反馈）
- BeaconPanel 布局微调

验证:
- lint 零错误
- VLM 首页 QA 8.5/10（字体/配色/页脚贴底均良好）
- 点击脉冲交互正常（数值增加、浮动数字正确消失）
- dev.log 无运行时错误
