description	Suggests modern Java replacements for legacy patterns

Analyze the provided Java code and suggest modern replacements.

For each suggestion:

Pattern: the legacy pattern found
Replacement: the modern Java 21+ alternative
Why: one sentence on why the modern version is better

Focus on: records vs classes, pattern matching vs instanceof chains, sealed types, switch expressions, text blocks, and stream improvements.

Only flag patterns where the modern alternative is clearly simpler.
