docs: document Codex Chat reasoning auto-detection

Browse Source 
Add a "Reasoning Auto-Detection" subsection to the Codex local-routing
manual (zh/en/ja) with the provider capability matrix, and record the
feature plus the streaming-usage and tool-call reasoning backfill fixes
in the changelog. Drop the removed Kimi For Coding preset from the
changelog's Codex Chat preset list.

### Added
- **Codex Chat Completions Routing**: Codex providers can now be served by upstreams that only speak the OpenAI Chat Completions API. CC Switch's local proxy converts Codex's outgoing Responses requests into Chat Completions and rebuilds the Chat response (both JSON and SSE) back into Responses shape, preserving `reasoning_content`, inline `<think>` blocks, streamed reasoning summaries, tool calls, and `previous_response_id` follow-ups. A bounded Codex Chat history cache restores tool calls before their tool outputs.
- **23 Codex Third-Party Provider Presets with Chat Routing**: Enabled Chat Completions routing with explicit model catalogs for major Chinese/Asian providers — DeepSeek, Zhipu GLM (+ en), Kimi, Kimi For Coding, MiniMax (+ en), StepFun (+ en), Baidu Qianfan Coding Plan, Bailian, ModelScope, Longcat, BaiLing, Xiaomi MiMo (+ Token Plan), Volcengine Agentplan, BytePlus, DouBao Seed, SiliconFlow (+ en), Novita AI, and Nvidia. Each preset declares its context window so the UI can size the model-mapping rows.
- **22 Codex Third-Party Provider Presets with Chat Routing**: Enabled Chat Completions routing with explicit model catalogs for major Chinese/Asian providers — DeepSeek, Zhipu GLM (+ en), Kimi, MiniMax (+ en), StepFun (+ en), Baidu Qianfan Coding Plan, Bailian, ModelScope, Longcat, BaiLing, Xiaomi MiMo (+ Token Plan), Volcengine Agentplan, BytePlus, DouBao Seed, SiliconFlow (+ en), Novita AI, and Nvidia. Each preset declares its context window so the UI can size the model-mapping rows.
- **Codex Model Mapping Table**: Codex provider forms now expose a model catalog (model + display name + context window per row) that is the single source of truth for the upstream model list, projected to `~/.codex/cc-switch-model-catalog.json`.
- **Codex Chat Providers in Stream Check**: Stream Check now probes Chat-format Codex providers against `/chat/completions` with a Chat-shaped body instead of `/v1/responses`, and aligns its URL fallback order with the production `CodexAdapter` (origin-only base URLs hit `/v1/<endpoint>` first) so a non-404 error on the bare path no longer flags a working provider as down.
- **Codex Chat Reasoning Auto-Detection**: When a Codex provider is served through Chat Completions routing, CC Switch now auto-detects the upstream's reasoning interface from its name, base URL, and model — injecting the correct thinking parameter (`thinking:{type}`, `enable_thinking`, `reasoning_split`, top-level `reasoning_effort`, or OpenRouter's native `reasoning:{effort}` object) with no manual setup. Aggregator/hosting platforms (OpenRouter, SiliconFlow) are matched platform-first, since the same model can expose different reasoning controls on different platforms. Providers that only expose a thinking on/off switch (Kimi, GLM, Qwen, MiniMax, MiMo, SiliconFlow) drop the effort *level* instead of forwarding an unsupported field — so changing Codex's reasoning effort has no effect for them — while providers with real effort tiers (DeepSeek, OpenRouter, and StepFun's `step-3.5-flash-2603` only) pass the level through. OpenRouter specifically uses the native `reasoning:{effort}` object, clamps `max` to `xhigh` (its enum has no `max`), and forwards an explicit `effort:"none"` so reasoning can be turned off.
- **Xiaomi MiMo Token Plan Presets**: Added Xiaomi MiMo Token Plan presets with specs aligned to the official documentation (#2803).
- **Claude Desktop Official Preset**: Added a Claude Desktop Official preset that restores the native Claude Desktop login, plus a localized Claude Desktop user guide (en / zh / ja).

- **Codex Model Catalog Infinite Render Loop**: Broke a bidirectional sync cycle between the catalog table and its parent state that caused severe UI jittering when adding or editing entries.
- **Codex Chat Preserves User-Selected Catalog Model**: A model the client selects from the catalog (e.g. via `/model`) is no longer overwritten by `config.toml`'s default model.
- **Codex Chat Reasoning and Cache Stability**: Restored a unique call-id fallback when Codex omits or rewrites `previous_response_id`, stopped deriving cache identity from `previous_response_id`, and canonicalized parseable JSON string payloads in tool conversions for stable prefix-cache reuse.
- **Codex Chat Streaming Usage Recovered**: The Responses-to-Chat conversion now injects `stream_options.include_usage` (merging into any client-provided `stream_options`) when a request is streaming, so OpenAI-compatible upstreams like Kimi and MiniMax emit the trailing usage chunk again. Previously their streamed token / cost / cache stats were recorded as zero on the Codex Chat path.
- **Codex Chat Tool-Call Reasoning Backfill**: Thinking models like Kimi/Moonshot and DeepSeek reject an assistant message that carries `tool_calls` without a non-empty `reasoning_content`. When cross-turn history recovery misses (proxy restart, ambiguous `call_id`, or a turn with no upstream reasoning), a placeholder `reasoning_content` is now backfilled in a final pass — genuine trailing reasoning still attaches first — so the request no longer fails with `reasoning_content is missing in assistant tool call message`.
- **Managed-Account Claude Takeover Auth**: Managed-account providers (GitHub Copilot / Codex OAuth) now drop token env keys and write only the `ANTHROPIC_API_KEY` placeholder when taking over Claude Live config, with an outbound guard that refuses to send the `PROXY_MANAGED` placeholder upstream.
- **Gemini Native Tool-Call Robustness**: Fixed `functionResponse.name` resolution (422) and `thought_signature` replay (400) for synthesized tool-call IDs in long multi-turn sessions (#2814).
- **Session Log Subagent Token Accounting**: `collect_jsonl_files()` now scans subagent JSONL logs that were previously missed, so subagent token usage is counted in session cost (session-log mode only) (#2821).
