feat(action): print matched URLs in includeFetch

[github-actions]

Closes #276

Applied changes based on Issue #276.

I’ve added a debug log inside the --fetch handling to print out all URLs detected in the prompt. Now when you run with --fetch, you’ll see a message like:

“Matched URLs for --fetch: https://example.com/foo, https://example.org/bar”

Details:

• In src/github/action.ts, inside the if (includeFetch) block
• Right after extracting urls = userPrompt.match(...)
• Emit core.info(Matched URLs for --fetch: ${urls.join(', ')});

Let me know if you’d like any tweaks (e.g. JSON formatting, additional context, etc.).
