📝 Walkthrough

Walkthrough

Adds Moonshot AI providers (moonshotai, moonshotai-cn) across schema, config types, gateway provider implementation (OpenAI-compatible request transform and validation), proxy auth/base-url routing, UI types, and localization strings.

Changes

Moonshot AI Provider Support

Layer / File(s)	Summary
Schema / API types src/config/entities/providers-schema.json, ui/src/lib/api/types.ts	Top-level provider type enum gains "moonshotai" and "moonshotai-cn". Conditional mapping routes these types to the openai_compatible config schema. TypeScript PROVIDER_TYPE_VARIANTS and Provider union include both variants with ApiBaseProviderConfig.
ProviderConfig & Config structs src/config/entities/providers.rs, src/gateway/providers/moonshot.rs	ProviderConfig adds MoonshotAi and MoonshotAiCn serde-tagged variants. New provider config structs include api_key and optional api_base. Schema validation tests updated to include both variants.
Provider implementation src/gateway/providers/moonshot.rs	Introduces provider module with IDENTIFIER / CN identifier, ProviderMeta and ChatTransform implementations, auth header builder, request transform pipeline that serializes requests, converts legacy functions/function_call → tools/tool_choice, validates tool_choice, applies model-specific sampling-field removal for kimi-k2.6/kimi-k2.5, and enforces numeric constraints (temperature, top_p, n). Unit tests cover metadata, auth, legacy conversions, model quirks, and validations.
Registry & proxy wiring src/gateway/providers/mod.rs, src/proxy/provider.rs	Exports new moonshot module and re-exports provider types/configs; adds MOONSHOT_AI and MOONSHOT_AI_CN identifiers; registers both providers in the default registry; proxy routing maps both variants to ProviderAuth::ApiKey and parses optional api_base. Tests added for registry and proxy auth/base-url behavior.
UI localization ui/src/i18n/locales/en.json, ui/src/i18n/locales/zh-CN.json	Added English and Chinese display strings for moonshotai and moonshotai-cn in model/provider selection and provider-type lists.

In `@ui/src/i18n/locales/en.json`:
- Around line 157-158: Update the label text for the "moonshotai-cn" locale key
so it is identical across all usages in the file: locate every "moonshotai-cn"
entry (including the other occurrence noted later in the file) and change its
value to the chosen canonical string "Moonshot AI (CN)" (or vice versa if your
project prefers no parentheses—ensure both occurrences match exactly).

In `@ui/src/i18n/locales/zh-CN.json`:
- Around line 157-158: Two entries for the same concept use inconsistent CN
label values; make the "moonshotai-cn" key consistent by updating both
occurrences of "moonshotai-cn" (and the related "moonshotai" pair if present) so
they share the identical string value (e.g., change the other instance to
"Moonshot AI (CN)" to match the first or vice versa) ensuring both keys
"moonshotai" and "moonshotai-cn" use the same CN label format across the file.
