docs: Change 'text' to 'content' in multimodal examples

[nauvalazhar]

🎯 Changes

Updated the documentation examples to use the content property instead of text.

This change aligns the documentation with the internal type definitions, where content is the expected field name. Using text in the docs could lead to type errors or confusion for developers implementing the library based on the examples.

✅ Checklist

• I have followed the steps in the Contributing guide.
• I have tested this code locally with pnpm run test:pr.

🚀 Release Impact

• This change affects published code, and I have generated a changeset.
• This change is docs/CI/dev-only (no release).

docs/guides/multimodal-content.md (3)

24-27: Documentation correctly aligned with type definitions.

The TextPart interface definition and usage examples are now consistent, showing content as the field name. This establishes the correct pattern for developers.

Also applies to: 66-66

---

248-248: Backward compatibility and type safety examples correctly updated.

The examples in critical sections (backward compatibility, type safety with assertMessages) now demonstrate the correct field name, ensuring developers implementing type-safe multimodal messages use the proper API.

Also applies to: 299-299

---

95-95: Provider examples consistently use the correct field name.

All provider-specific examples (OpenAI, Anthropic, Gemini, Ollama) correctly use the content field for text parts, matching the TypeScript type definitions where TextPart is defined with content: string.
