Fix menuSuggestionFlow return type and set default Gemini model in docs

[nikhil478]

Summary

This PR fixes the menuSuggestionFlow example in src/content/docs/docs/flows.mdx to correctly return a pointer to MenuItem and sets a default Gemini model in the initialization example.

Changes

1. Set Default Model

Added:

genkit.WithDefaultModel("googleai/gemini-2.5-flash"),

This makes the example explicitly configure a default model, improving clarity and ensuring consistent behavior in the documentation.

---

2. Fix menuSuggestionFlow Return Type

Updated the flow signature from:

(MenuItem, error)

to:

(*MenuItem, error)

The generated item returned by:

genkit.GenerateData[MenuItem](...)

is a pointer, so the flow should return *MenuItem instead of a struct value. This corrects the documentation to match the actual behavior and prevents confusion for developers copying the example.

---

Why This Change?

• Ensures the documentation reflects the correct return type.
• Prevents type mismatch confusion when implementing the example.
• Makes the sample code production-accurate and consistent.

---

Impact

• Documentation-only change
• No runtime or API changes
• Improves correctness and clarity of example code

Summary of Changes

Hello @nikhil478, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the genkit documentation by addressing two key areas in the flows.mdx example. It ensures that the menuSuggestionFlow's return type is correctly specified as a pointer, preventing potential type mismatch errors for developers. Additionally, it improves the initialization example by explicitly setting a default Gemini model, making the documentation more robust and easier to follow for new users.

Highlights

• Documentation Accuracy: Corrected the menuSuggestionFlow example in flows.mdx to accurately reflect that it returns a pointer to MenuItem (*MenuItem), aligning with the actual behavior of genkit.GenerateData.
• Example Clarity: Added an explicit default Gemini model (googleai/gemini-2.5-flash) to the genkit.Init example, enhancing clarity and ensuring consistent behavior for users following the documentation.

Changelog

• src/content/docs/docs/flows.mdx
  • Added genkit.WithDefaultModel("googleai/gemini-2.5-flash") to the genkit.Init call.
  • Updated the menuSuggestionFlow signature to return *MenuItem instead of MenuItem.

Code Review

The pull request correctly updates the Go initialization example to include a default model, which is a helpful improvement for clarity. However, the change to the menuSuggestionFlow return type in the Go example (line 249) introduces a type mismatch. The author's assumption that genkit.GenerateData[MenuItem] returns a pointer is incorrect; it returns a struct value. Reverting this change fixes the compilation error and maintains consistency with other examples in the documentation.
