feat(ai-openrouter): update model catalog from OpenRouter API (#400)

* feat(ai-openrouter): update model catalog from OpenRouter API

Regenerate model-meta.ts from the current OpenRouter /api/v1/models
endpoint (346 models total, +57 new, -59 deprecated).

Notable additions:
- openai/gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, gpt-5.4-pro
- anthropic/claude-sonnet-4.6, claude-opus-4.6
- z-ai/glm-5-turbo, glm-5, glm-4.7-flash
- xiaomi/mimo-v2-pro, mimo-v2-omni
- minimax/minimax-m2.7, minimax-m2.5
- google/gemini-3.1-flash-lite-preview, gemini-3.1-pro-preview
- mistralai/mistral-small-2603
- moonshotai/kimi-k2.5
- qwen/qwen3.5-* series

Fixes in conversion script:
- Map snake_case supported_parameters from the API to camelCase
  keys matching OpenRouterBaseOptions (frequency_penalty →
  frequencyPenalty, etc.)
- Skip duplicate openrouter/auto entries when the model is already
  in the API catalog

Other changes:
- Add parallelToolCalls to OpenRouterBaseOptions
- Update image-adapter test to use non-deprecated model ID

* chore: add changeset and apply prettier formatting

- Add minor changeset for @tanstack/ai-openrouter
- Apply prettier formatting to model-meta.ts and scripts

* fix: filter excludedParams from runtime supports array

The supports array in generated model metadata included tools,
reasoning_effort, and structured_outputs which were already filtered
from the TypeScript Pick<> types, creating a runtime/type mismatch.

* fix: align parallelToolCalls JSDoc across interfaces

Add missing @default true annotation to OpenRouterBaseOptions to
match OpenRouterCommonOptions.

* ci: apply automated fixes

* chore: refresh model catalog from OpenRouter API

+1 new model (kwaipilot/kat-coder-pro-v2), -2 removed free variants
(mistralai/mistral-small-3.1-24b-instruct:free, qwen/qwen3-4b:free),
plus pricing/parameter updates across existing models.
