+- Replaced the Spigot-only Bungee dialog types that were absent from production with Purpur's supported Paper dialog API.
+- Compiled and tested against the exact Purpur 26.2 build 2618 API with Java 25, and updated both CI workflows to use Java 25.
+- Preserved unit-test coverage through server-independent dialog specifications and adapted Bukkit test fixtures to Purpur's registry-aware API behavior.
+- Verified 128 tests and the Java 25 plugin artifact with `./gradlew clean check jar`.
