0.1.45 更新后第三方模型服务商全线报错（Console Go/DeepSeek/100hub/枣树）

## 现象

更新到 0.1.45-hotfix（2026-08-12 15:17 安装）后，所有非官方模型服务商无法对话，均在会话报错横幅出现：

1. **Console Go（opencode-go）**
`Error from provider (Console Go): Upstream request failed: [invalid_request_error] Unsupported custom tool: 'exec'. Only 'apply_patch' is supported.`

2. **DeepSeek（deepseek）**
`Unsupported custom tool: 'exec'. Only 'apply_patch' is supported.`（providerId=deepseek）

3. **100hub**
`unexpected status 503 Service Unavailable: Service temporarily unavailable, url: http://127.0.0.1:63374/responses`

4. **枣树（provider-1l79y61）**
`stream disconnected before completion: [ArrayParam] [input[27].content] [array_above_max_length] Invalid 'input[27].content': array too long. Expected an array with maximum length 0, but got an array with len...`

另有 litellm 桥接层提示：
- `Responses feature is not supported by the Chat Completions bridge: tools[3].web_search`
- `Responses feature is not supported by the Chat Completions bridge: input[0].content`

## 时间线

- 15:17:57 安装 cindy-0.1.45-hotfix.zip，15:18:14 完成重启
- 15:20:01 起 opencode-go 首次报错
- 15:21:58 起 deepseek 首次报错（Unsupported custom tool: exec）
- 15:44:02 100hub 503
- 16:26 前后 枣树 array_above_max_length
- 16:47 起新开 xd 通道会话全部正常

## 诊断

- 本地设置与服务商注册均完好（provider-order-prefs.json、custom_providers 表、key 文件均在）
- 错误来自上游网关拒绝请求，非本地客户端拦截
- 疑似 0.1.45 调整了发给第三方网关的工具清单（包含 exec / web_search 等），第三方网关不识别直接拒绝
- 官方 xd 通道不经过第三方网关，因此不受影响

## 建议

- 请将第三方网关（opencode.ai / api.deepseek.com / litellm 桥接）的工具白名单与客户端工具清单对齐
- 或对不支持的网关在本地降级为仅 apply_patch + 文本回复，避免上游 400 错误直接抛给用户
- 应急方案：用户可切换官方 xd 通道继续使用

Start by reproducing the 0.1.45-hotfix failures with the affected providers, then compare the request tool payload with the provider and litellm bridge capabilities. The report names provider-order-prefs.json, the custom_providers table, and key files as configuration checks. Done means unsupported tools no longer cause third-party requests to fail, while the official xd channel remains unaffected.
