Add generative AI examples and register SplashKit author

[222448082Ashen]

Description

Splashkit Function: generate_reply

Overview of example functionality:
This PR adds an integrated usage example called Interactive AI Terminal (Single-Turn AI). The example opens a window, reads a user prompt using read_line, generates a single AI-style response using generate_reply, and displays the response in terminal and on-screen text.
For environments where the Python binding does not expose generate_reply, the Python variant now falls back to a local reply so the example still runs.

Example Output:
Added screenshot asset at generate_reply-1-example.png

Looks good to me. The PR adds a clear and focused generate_reply usage example across C++, C#, and Python, and the example demonstrates the function in a simple single-turn interactive AI terminal format.

The code is easy to follow, uses SplashKit functions appropriately, and includes the supporting title text and screenshot asset. The author metadata update in astro.config.mjs also looks reasonable for registering the SplashKit author.

No blocking issues from my review. Approved.

Reviewed the PR and the implementation looks solid overall. The generative AI examples are consistent across C#, C++, and Python, and the UI demonstration is easy to follow. The SplashKit author registration in astro.config.mjs is also correctly added and improves configuration consistency.

One minor optional suggestion: the C++ example uses string without explicitly including <string> or using std::string, which may cause issues in some compiler environments.

Apart from that, everything looks good — approved for merge.
