chore: 移除 ccshareResume stub 及 main.tsx 的 ccshare fast-path

- 删除 src/utils/ccshareResume.ts（parseCcshareId 恒返回 null、loadCcshare 恒抛错的 stub）
- 同步移除 src/main.tsx 中 USER_TYPE === 'ant' 守卫下的 if (ccshareId) {...} else {...} 双分支
- 提升 else 块（文件路径 resume 处理）为直接进入 if (options.resume) 块内

ccshare 是 Anthropic 内部特性（go/ccshare URL），stub 未实现导致 ccshareId 恒为 null，整个 ccshare 分支永不进入；保留的文件路径 resume 路径不变。
