Release v0.3.0 · Jakevin/CC-Adapter

v0.3.0

支援多個 Provider 同時配置：透過 config.toml 的 [providers.*] 定義多個供應商（chatgpt / openai / anthropic-compatible 等）。
新增 anthropic-compatible Provider 類型：直接透過 Anthropic Messages API 格式轉發到相容後端，只需設定 base_url + api_key。
模型路由表改為結構化：使用 [models] + [models.routing]，每個 key 映射到 { provider, model }。
支援「最長前綴匹配」模型路由：models.routing 的 key 可以只寫「型號前綴」（如 claude-haiku-4-5），自動匹配 claude-haiku-4-5-20251001 等帶日期後綴的變體。
保留舊版單一 Provider 格式：仍支援原本的 [provider] + models.mapping，內部會自動轉成多 Provider 結構。

supports_streaming 設定啟用：在每個 Provider 的 config 裡用 supports_streaming 控制是否對後端開啟 stream；預設建議 false，由 Adapter 統一模擬 SSE。
請求失敗時在錯誤訊息中加入完整 API URL（OpenAI / ChatGPT / Anthropic-compatible），方便排查 404 / 路徑錯誤。
針對 Anthropic-compatible 後端回傳 SSE 的情況，強制 stream=false 時期望 JSON 回應；若仍為 SSE，會在錯誤訊息中附上 Raw body 以方便 debug。

回應型別新增 thinking 變體：MessagesResponse.content 現在支援 type: "thinking"，包含 thinking 與可選的 signature 欄位。
Anthropic-compatible 回應可正確解析含 thinking 的 content 陣列，不再因未知 variant 而失敗。
SSE 串流輸出時，thinking 會用 Anthropic 官方 SSE 事件格式（content_block_start + thinking_delta + content_block_stop），而不是當作一般文字輸出；UI 可以選擇隱藏或特殊處理 thinking，而不會顯示 <thinking>...</thinking> 純文字。

更新 config-example.toml：展示多 Provider 配置（含 supports_streaming 與前綴路由註解）。
更新 README（英文 / 繁中 / 簡中）：說明多 Provider 結構、models.routing 前綴匹配規則、Anthropic-compatible Provider、thinking 區塊行為。

Support configuring multiple providers at once via [providers.*] in config.toml (e.g. chatgpt, openai, anthropic-compatible).
New anthropic-compatible provider type: forwards Anthropic Messages API requests directly to compatible backends by configuring base_url + api_key.
Structured model routing: use [models] + [models.routing], each key maps to { provider, model }.
Longest-prefix model routing: models.routing keys can be “family prefixes” (e.g. claude-haiku-4-5), automatically matching dated variants like claude-haiku-4-5-20251001.
Legacy single-provider format still supported: original [provider] + models.mapping is normalized internally into the same multi-provider structure.

supports_streaming flag activated per provider: controls whether the adapter asks the backend for streaming responses; recommended false so the adapter simulates SSE uniformly.
Include full API URL in provider error messages (OpenAI / ChatGPT / Anthropic-compatible) to quickly diagnose 404 and path issues.
For Anthropic-compatible backends that return SSE while stream=false, parse failures now include the full raw body to aid debugging.

Response type extended with thinking variant: MessagesResponse.content now supports type: "thinking" with thinking text and optional signature.
Anthropic-compatible JSON responses containing thinking blocks can be deserialized correctly, instead of failing on unknown variants.
When emitting SSE, thinking blocks are forwarded using Anthropic’s official SSE schema (content_block_start + thinking_delta + content_block_stop), not as plain text; UIs can hide or specially render thinking instead of showing it inline as <thinking>...</thinking>.

Updated config-example.toml to showcase multi-provider configuration, supports_streaming, and prefix-based routing with detailed comments.
Updated README (EN / ZH-HANT / ZH-HANS) to document multi-provider architecture, models.routing resolution rules, Anthropic-compatible providers, and thinking block behavior.
