Support GPT-5.1: smarter, faster, and more conversational for complex tasks (#1783)

Added to OpenAI and Azure GPT-5.1: adaptive reasoning GPT-5.1-codex: advanced coding workflows GPT-5.1-codex-mini: compact and efficient  --- ## Summary by cubic Added support for OpenAI and Azure GPT-5.1, including GPT-5.1 Codex and Codex Mini, for smarter conversations and better coding tasks. All models use a 400k context window, require temperature 1, and leave max output tokens unspecified to align with API behavior. <sup>Written for commit 9788541c88732aa7d522fc70bfb20f22c3544982. Summary will update automatically on new commits.</sup>   --- > [!NOTE] > Adds GPT-5.1, GPT-5.1 Codex, and Codex Mini to OpenAI and Azure model catalogs with 400k context and temperature 1 (max output tokens unspecified). > > - **Model registry updates (`src/ipc/shared/language_model_constants.ts`)**: > - **OpenAI**: > - Add `gpt-5.1`, `gpt-5.1-codex`, `gpt-5.1-codex-mini` (400k `contextWindow`, `temperature: 1`, `maxOutputTokens: undefined`). > - Keep existing `gpt-5`, `gpt-5-codex`, `gpt-5-mini`, `gpt-5-nano`, `o4-mini`. > - **Azure**: > - Add `gpt-5.1`, `gpt-5.1-codex`, `gpt-5.1-codex-mini` with matching settings (400k `contextWindow`, `temperature: 1`). > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 9788541c88732aa7d522fc70bfb20f22c3544982.
