feat: 从 PokeAPI 批量导入物种数据，替换硬编码

- 新增 pokedex-data.ts：1024 个物种的 baseExperience、EV yield、growthRate、captureRate、baseHappiness、hatchCounter
- 新增 fetch-pokedex-data.ts：PokeAPI 数据抓取脚本（可重复运行）
- 新增 fetch-species-names.ts：多语言名称抓取脚本（中/日/英）
- species.ts 改为使用 pokedex-data 替代硬编码 supplement 条目
- 解决 #1 XP 数据源、#2 EV 数据源、#13 Growth Rate 覆盖不全问题
