* feat: add MiMo (Xiaomi) as AI provider
* fix: correct MiMo default base URL, suggested models, and reasoning support
- Default base URL was the China Token Plan endpoint (tp- keys only);
switch to https://api.xiaomimimo.com/v1 which works with standard
pay-as-you-go sk- keys. Token Plan users can override in settings.
- Replace deprecated mimo-v2-flash suggestion with mimo-v2.5
(v2 series was deprecated on 2026-06-30).
- Use createDeepSeek instead of createOpenAI so reasoning_content is
passed back during multi-turn tool calls (MiMo returns 400 without
it), matching the existing Kimi implementation.
- Add mimo to SINGLE_SYSTEM_PROVIDERS so system messages are merged.
- Fold validate-model case into the shared OpenAI-compatible group.
- Drop the Bot icon special case; models.dev serves a real xiaomi logo
via PROVIDER_LOGO_MAP.
- Document MIMO_API_KEY/MIMO_BASE_URL in env.example and
docs/{en,cn,ja}/ai-providers.md.
* feat: show base URL hint for MiMo in provider settings
MiMo has two endpoints tied to key type: pay-as-you-go keys (sk-...)
use the default api.xiaomimimo.com/v1, while Token Plan keys (tp-...)
require token-plan-cn.xiaomimimo.com/v1. Surface this under the Base
URL field like the existing MiniMax hint, in all four locales.
