Walkthrough

This PR extends OpenAI and Azure OpenAI provider configurations by adding a new reasoningSummary field that controls whether the model returns reasoning output. The field accepts values "auto", "detailed", or "none" (defaulting to "auto"), and is implemented consistently across documentation, schemas, type definitions, and runtime handling code.

Changes

Cohort / File(s)	Summary
Changelog & Documentation CHANGELOG.md, docs/docs/configuration/language-model-providers.mdx	Added reasoningSummary field to changelog and updated provider documentation with field descriptions, allowed values, and example configurations for both OpenAI and Azure OpenAI providers.
Type Definitions packages/schemas/src/v3/index.type.ts, packages/schemas/src/v3/languageModel.type.ts	Added optional reasoningSummary?: string property to AzureLanguageModel and OpenAILanguageModel interfaces with documentation of accepted values and default behavior.
JSON Schema Definitions packages/schemas/src/v3/index.schema.ts, packages/schemas/src/v3/languageModel.schema.ts, docs/snippets/schemas/v3/*.schema.mdx, schemas/v3/languageModel.json	Extended reasoningEffort examples to include "none" value and added new reasoningSummary string property with description and examples ("auto", "detailed", "none") across all applicable provider configuration schemas.
Runtime Implementation packages/web/src/features/chat/utils.server.ts	Added conditional handling to derive reasoningSummary from configuration (defaulting to 'auto') and include it in OpenAI-style provider options only when value is not 'none'.
