CC Desktop Switch v1.0.25

English

This patch release focuses on issue-batch stability for the Python line.

Added a billing header rectifier for Claude Code through third-party gateways. It removes only the dynamic x-anthropic-billing-header system block before forwarding, which can improve prompt-cache stability on compatible relays.
Added an advanced setting to disable the billing header rectifier when troubleshooting unusual gateways.
Updated Xiaomi MiMo 1M presets so the checkbox maps Opus, Sonnet, and Haiku slots to mimo-v2.5-pro and marks the exposed Claude routes with supports1m.
Kept DeepSeek 1M Haiku mapping intact when applying the preset option.
Changed the missing Claude Code helper signal on macOS/Windows from a dashboard warning to an info-level diagnostics item. Normal third-party gateway chat is not treated as failed by this helper state.
Kept diagnostics export as UTF-8 JSON and preserved Chinese diagnostic text without exposing secrets.
Absorbed provider preset JSON extraction and CCDS_CONFIG_DIR support from community PRs after review.

本次是 Python 稳定线的问题批量修复。

新增 Claude Code 第三方 gateway 的 billing header 清理器。转发前只移除动态 x-anthropic-billing-header system 块，用于降低兼容中转的 prompt cache 被打散概率。
在高级兼容设置里增加开关，排查特殊中转时可以关闭该清理器。
更新 Xiaomi MiMo 1M 预设，勾选后会把 Opus、Sonnet、Haiku 槽位映射到 mimo-v2.5-pro，并给暴露给 Claude Desktop 的 route 写入 supports1m。
保持 DeepSeek 1M 预设里的 Haiku 映射不丢失。
将 Claude Code helper 缺失从首页警告改为诊断页 info 提示。普通第三方 gateway 聊天不再因为 helper 状态被判定为失败。
诊断包继续以 UTF-8 JSON 导出，中文诊断文本不乱码，同时保持密钥脱敏。
审查后吸收社区 PR 里的 provider preset JSON 拆分和 CCDS_CONFIG_DIR 支持。
