Update language model constants with latest configurations (#2633)

## Summary - Update language model constants with latest model configurations and pricing - Add support for new model versions across multiple providers - Improve model descriptions and configuration parameters ## Test plan - Verify that the application loads with all model configurations - Test model selection in the UI - Confirm no TypeScript or lint errors 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2633" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>   --- > [!NOTE] > **Low Risk** > Primarily updates configuration/constants for model selection; main behavioral change is the expanded free-model name matching which could alter which OpenRouter models are used in fallback. > > **Overview** > Adds the new Anthropic model `claude-opus-4-6` (with updated token limits/pricing metadata) to the selectable model options. > > Refreshes OpenRouter model options by introducing a generic `openrouter/free` entry, adding `z-ai/glm-5`, tweaking `glm-4.7` description, and removing older explicit free-model entries and `moonshotai/kimi-k2-0905`. Updates `FREE_OPENROUTER_MODEL_NAMES` to treat both `:free` and `/free` model names as free, which changes which models can be selected in the auto free fallback. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit d192033357d87355a9d414269a19a348c3faef6d.

Adds new models and improves free model detection for OpenRouter. - **New Features** - Added Claude Opus 4.6 (1M context, 32k max output). - Added OpenRouter “free” model and Z‑AI GLM 5; updated GLM 4.7 description. - Updated context windows, temperatures, and pricing; removed deprecated free entries and Kimi K2 0905. - **Bug Fixes** - Free model detection now supports names ending with “/free” (not just “:free”). <sup>Written for commit d192033357d87355a9d414269a19a348c3faef6d. Summary will update on new commits.</sup>
