📄 Description

Summary by cubic

Add a client-side i18n plugin that translates API error codes into localized messages, configurable via a translations map. Improves user-facing error text without server changes.

  • New Features
    • Introduced translationClientPlugin that intercepts non-OK responses and maps error code -> localized message (updates data.message, data.error.message, and statusText).
    • getClientConfig registers the plugin; it activates only if translations are provided.
    • Added translations option to BetterAuthClientOptions (typed against BASE_ERROR_CODES with support for custom codes).
    • Added unit test covering code-to-message translation (e.g., USER_NOT_FOUND -> 用户找不到).

Written for commit e721907ecf. Summary will update automatically on new commits.
