Add reverse mappings for original tool names and improve error logging

- Introduced reverse mapping logic for tool names in translators to restore original names when shortened.
- Enhanced error handling by logging API response errors consistently across handlers.
- Refactored request and response loggers to include API error details, improving debugging capabilities.
- Integrated robust tool name shortening and uniqueness mechanisms for OpenAI, Gemini, and Claude requests.
- Improved handler retry logic to properly capture and respond to errors.

+# Management API
+
+Base path: `http://localhost:8317/v0/management`
+
+This API manages the CLI Proxy API’s runtime configuration and authentication files. All changes are persisted to the YAML config file and hot‑reloaded by the service.
+
+Note: The following options cannot be modified via API and must be set in the config file (restart if needed):
+- `allow-remote-management`
+- `remote-management-key` (if plaintext is detected at startup, it is automatically bcrypt‑hashed and written back to the config)
+
+## Authentication
+
+- All requests (including localhost) must provide a valid management key.
+- Remote access requires enabling remote management in the config: `allow-remote-management: true`.
+- Provide the management key (in plaintext) via either:
+  - `Authorization: Bearer <plaintext-key>`
+  - `X-Management-Key: <plaintext-key>`
+
+If a plaintext key is detected in the config at startup, it will be bcrypt‑hashed and written back to the config file automatically.
+
+## Request/Response Conventions
+
+- Content-Type: `application/json` (unless otherwise noted).
+- Boolean/int/string updates: request body is `{ "value": <type> }`.
+- Array PUT: either a raw array (e.g. `["a","b"]`) or `{ "items": [ ... ] }`.
+- Array PATCH: supports `{ "old": "k1", "new": "k2" }` or `{ "index": 0, "value": "k2" }`.
+- Object-array PATCH: supports matching by index or by key field (specified per endpoint).

+- Changes are written back to the YAML config file and hot‑reloaded by the file watcher and clients.
+- `allow-remote-management` and `remote-management-key` cannot be changed via the API; configure them in the config file.

+# 管理 API
+
+基础路径：`http://localhost:8317/v0/management`
+
+该 API 用于管理 CLI Proxy API 的运行时配置与认证文件。所有变更会持久化写入 YAML 配置文件，并由服务自动热重载。
+
+注意：以下选项不能通过 API 修改，需在配置文件中设置（如有必要可重启）：
+- `allow-remote-management`
+- `remote-management-key`（若在启动时检测到明文，会自动进行 bcrypt 加密并写回配置）
+
+## 认证
+
+- 所有请求（包括本地访问）都必须提供有效的管理密钥.
+- 远程访问需要在配置文件中开启远程访问： `allow-remote-management: true`
+- 通过以下任意方式提供管理密钥（明文）：
+  - `Authorization: Bearer <plaintext-key>`
+  - `X-Management-Key: <plaintext-key>`
+
+若在启动时检测到配置中的管理密钥为明文，会自动使用 bcrypt 加密并回写到配置文件中。
+
+## 请求/响应约定
+
+- Content-Type：`application/json`（除非另有说明）。
+- 布尔/整数/字符串更新：请求体为 `{ "value": <type> }`。
+- 数组 PUT：既可使用原始数组（如 `["a","b"]`），也可使用 `{ "items": [ ... ] }`。
+- 数组 PATCH：支持 `{ "old": "k1", "new": "k2" }` 或 `{ "index": 0, "value": "k2" }`。
+- 对象数组 PATCH：支持按索引或按关键字段匹配（各端点中单独说明）。

+### OpenAI Compatibility Providers
+
+Configure upstream OpenAI-compatible providers (e.g., OpenRouter) via `openai-compatibility`.
+
+- name: provider identifier used internally
+- base-url: provider base URL
+- api-keys: optional list of API keys (omit if provider allows unauthenticated requests)
+- models: list of mappings from upstream model `name` to local `alias`
+
+Example:
+
+```yaml
+openai-compatibility:
+  - name: "openrouter"
+    base-url: "https://openrouter.ai/api/v1"
+    api-keys:
+      - "sk-or-v1-...b780"
+      - "sk-or-v1-...b781"
+    models:
+      - name: "moonshotai/kimi-k2:free"
+        alias: "kimi-k2"
+```
+
+Usage: 
+
+Call OpenAI's endpoint `/v1/chat/completions` with `model` set to the alias (e.g., `kimi-k2`). The proxy routes to the configured provider/model automatically.
+
+Also, you may call Claude's endpoint `/v1/messages`, Gemini's `/v1beta/models/model-name:streamGenerateContent` or `/v1beta/models/model-name:generateContent`.
+
+And you can always use Gemini CLI with `CODE_ASSIST_ENDPOINT` set to `http://127.0.0.1:8317` for these OpenAI-compatible provider's models.

+对于项目前期的确有很多用户使用上遇到各种各样的奇怪问题，大部分是因为配置或我说明文档不全导致的。
+
+对说明文档我已经尽可能的修补，有些重要的地方我甚至已经写到了打包的配置文件里。
+
+已经写在 README 中的功能，都是**可用**的，经过**验证**的，并且我自己**每天**都在使用的。
+
+可能在某些场景中使用上效果并不是很出色，但那基本上是模型和工具的原因，比如用 Claude Code 的时候，有的模型就无法正确使用工具，比如 Gemini，就在 Claude Code 和 Codex 的下使用的相当扭捏，有时能完成大部分工作，但有时候却只说不做。
+
+目前来说 Claude 和 GPT-5 是目前使用各种第三方CLI工具运用的最好的模型，我自己也是多个账号做均衡负载使用。
+
+实事求是的说，最初的几个版本我根本就没有中文文档，我至今所有文档也都是使用英文更新让后让 Gemini 翻译成中文的。但是无论如何都不会出现中文文档无法理解的问题。因为所有的中英文文档我都是再三校对，并且发现未及时更改的更新的地方都快速更新掉了。
