v0.8.1: 探险平衡 + 信标系统扩展（周挑战 + 信标链）

P1-a 探险 BOSS 胜率平衡 + 能量恢复（expedition.ts + config.ts + gameStore.ts + ExpeditionPanel.tsx）:
- combatWinRate: scale 8→4, floor 0.25→0.35（基础力10对BOSS胜率 25%→35-45%）
- BOSS 难度 5-7→3-5（配合新公式基础胜率达 45-55%）
- computeEnergyRegenInterval(state): 动态恢复间隔
  - exp_2 解锁 -30%, exp_3 解锁 -20%, 探索力属性 -最高30%
  - 下限 12s（原固定 45s）
- computeEnergyRegen 接受 intervalSec 参数
- gameStore tick 传入动态间隔
- config.ts: exp_2/exp_3 描述加'能量恢复 +30%/+20%'
- ExpeditionPanel: 显示实际恢复速度 + '已加速'标记

P1-b 信标系统扩展（beacon.ts + BeaconPanel.tsx + gameStore.ts）[subagent 9-b]:
- 周挑战: getWeekKey ISO 8601 + FNV-1a 种子确定性生成
  - 难度强制 anomaly 60%/singular 40%, goal 日挑战×3-5倍
  - 完整进度/领奖/排行榜推送(isWeekly标记)
- 信标链: 4里程碑(3/7/14/30天) + grace续命机制(每链1次)
  - recordChainCompletion 核心断链/续命逻辑
  - 奖励 50→680洞见递增
- BeaconPanel: 周挑战fuchsia主题 + 信标链amber→rose渐变里程碑节点
- gameStore: trackBeacon升级 + claimWeeklyBeacon/claimChainReward actions
- VLM 8/10, lint零错误, 5场景bun测试全PASS
