Closes: #9344

Description

This PR attempts to address Issue #9344 by correcting the context window limit for Mistral's codestral-latest model.

The codestral-latest model was incorrectly configured with a context window of 256,000 tokens when the official Mistral documentation specifies it should be 131,000 tokens (128k in practice).

Updated the contextWindow value in packages/types/src/providers/mistral.ts from 256,000 to 131,000.

Test Procedure

• Ran type checking: npm run check-types - passed
• Ran linting: npm run lint - passed
• Ran all tests in packages/types: npx vitest run - 139 tests passed
