v0.9 工单修复: 4 bug + 4 玩法改进

Gitea Issue #2 修复:
Bug:
1. 探险只能一次 → 能量恢复 45→20s, 初始能量 3→5, 上限 5→8
   新增 lastExpeditionSummary 显示上次结果
   新增 dismissExpedition action
2. 元素偏移/遮挡 → 标签页 grid-cols-8 → 响应式 grid-cols-4/sm:8
3. 成就UI遮挡 → max-h 440→520, min-h 提高
4. 提示框遮挡 → toast top-0→top-14 避开 header, TOAST_LIMIT 1→3

玩法改进:
1. 中央晶体球 → 下方新增 4 指标收益面板(产能/脉冲/连击/仓库)
2. 技术树 12→20 节点 (每分支 3→5 级)
3. 成就解锁 → 全屏居中特效通知 (framer-motion 弹窗)
4. 叙事融入 → 新建 narrative.ts, 脉冲/技术树注入世界观文本
