16-17: Consider updating to Zod v4 unified error parameter.

The current error message syntax uses string literals as the second parameter. Zod v4 introduces a unified error parameter for more flexible error customization.

Apply this diff to align with Zod v4 best practices:

     text: z
         .string()
         .trim()
-        .min(50, "Text too short to summarize (minimum 50 characters)")
-        .max(50000, "Text too long (maximum 50,000 characters)"),
+        .min(50, {
+            error: () => "Text too short to summarize (minimum 50 characters)"
+        })
+        .max(50000, {
+            error: () => "Text too long (maximum 50,000 characters)"
+        }),

Based on library documentation.

78-78: Consider using SummaryStyles type for stronger type safety.

The style parameter is currently typed as string, requiring a type assertion at line 90. Using the SummaryStyles type would eliminate the need for the assertion and provide compile-time safety.

Apply this diff to improve type safety:

     private buildSystemPrompt(
         maxLength: number,
-        style: string,
+        style: SummaryStyles,
         language: string,
     ): string {

Then simplify line 90:

-        return `You are a professional text summarizer. ${styleInstructions[style as keyof typeof styleInstructions]}
+        return `You are a professional text summarizer. ${styleInstructions[style]}
