v0.24.10 -> v0.24.11
Summary
Agent selection switches from a single-name pick to a prioritized chain so the runtime cascades to the next candidate when a provider call fails mid-turn. Optional provider tools always register at startup and are hidden per-turn based on credential presence, keeping the toolset coherent as keys come and go. Closes a nil-agent crash path and a Codex OAuth error decode bug.
翻譯
代理選擇從單一候選改為優先順序鏈，turn 中遇到 provider 失敗時 runtime 會自動接力下一個候選。選用工具改為啟動時一律註冊、每輪依金鑰存在與否決定可見性，金鑰新增或撤銷時 toolset 即時保持一致。同時補上 nil agent 崩潰路徑與 Codex OAuth error 解碼修正。
Changes
FEAT
- Add agent fallback resolution and runtime failover [aa0835a]
翻譯
- 代理選擇器改回傳逗號分隔的優先順序鏈（首選在前），
ExecData新增FallbackAgents；exec.Run在主要 agent 送訊失敗時依序試用後備，TUI／Discord／Telegram／routes 一同接通 failover plumbing
UPDATE
- Always register optional tools and gate them by credential checks [18a0ab7]
翻譯
- 拿掉
gemini/stt、gemini/youtube、openaiCodex/image2、telegram/tool、discord/toolregister ���的 startup credential 檢查，工具一律註冊；exec.Execute改在每輪依keychain.Get與cfg.{T,D}Enabled動態 appenddata.ExcludeTools，與 KuraDB 既有 per-turn exclusion 路徑對齊
FIX
- Fix nil agent fallback and Codex OAuth error parsing [7b8bc0a]
翻譯
exec.Run在SelectAgent回 nil 時改回明確錯誤訊息（提示跑agen model add），不再 nil deref；SelectAgent在bot == nil時回registry.Fallback；Codex OAuthexchangeCode／refresh修正 error response 欄位解析
