feat(compute): 重新发布 Claude 订阅 provider（anthropic-claude），presetDataVersion → 84 (#70)

#47/#48/#49 曾因 credentialSource 硬 enum 毒丸老客户端而被 #50 回滚。毒丸根因已由
客户端 desirecore#1021 系统性修复（credentialSource 改开放 string + 合并 salvage +
能力门控降级），claude-oauth 检测器与 SDK 网关由 desirecore#1008 提供，
requiredClientVersion 运行时门槛由 desirecore#1038 提供，三者同在 v10.0.83 发布。

本次重新发布相较 #47 的变化：
- 声明 requiredClientVersion = 10.0.83，低版本客户端优雅门控为「需更新客户端」
- displayName 去掉冗余 (订阅) 后缀，对齐 #58 的 Codex 命名约定
- 文件名 anthropic-claude.json 与 _index.json basename 一致（#48 的修正一并纳入）
