Sets the default AI chat model to anthropic/claude-sonnet-4.6 and the default text-generation (WYSIWYG writing) model to anthropic/claude- haiku-4.5 across all three layers where defaults live: the backend hydrateDefaults() fallback in AiConfigurationService, the frontend createDefaults() in AiConfigurationForm, and the docblock example in AiTextGenerationService. Refreshes the DriverRegistryProvider suggested-model list to only include recent models from Anthropic (Sonnet 4.6, Haiku 4.5, Opus 4.6), OpenAI (GPT-5.4, GPT-5.4 mini), Google (Gemini 3.1 Pro preview, Gemini 3.1 Flash Lite preview) and Z.AI (GLM 5.1, GLM 4.7 Flash). Drops GPT-4o, Claude 3.5, Gemini 1.5 and Llama 3.3. The underlying config still accepts any OpenRouter model ID, so the suggested list is purely a UX surface — existing companies with a custom ai_chat_model retain their value untouched.

/**
|
|
* Stateless one-shot text generation for the WYSIWYG popup.
|
|
*
|
|
* Much simpler than the chat assistant — no conversation state, no tool calls,
|
|
* no history. Takes a user-authored instruction plus optional surrounding
|
|
* context (e.g. "here's the current editor content") and returns a single
|
|
* generated text blob the frontend can insert into the editor.
|
|
*
|
|
* The text-generation role is distinct from chat in two places:
|
|
* - AiConfigurationService.text_generation_enabled gates availability
|
|
* - ai_text_generation_model picks which model to use
|
|
*
|
|
* That means an instance can use a cheap fast model for one-shot writing
|
|
* (anthropic/claude-haiku-4.5) while pointing chat at a smarter model
|
|
* (anthropic/claude-sonnet-4.6) without config gymnastics.
