feat(spawn): migrate distribution to Java 25 and Purpur

BREAKING CHANGE: New releases require Java 25/Purpur 26.2 and use purpur-trigger-spawn-<version>.jar. Runtime TriggerSpawn identity, persisted progression/cooldowns and world spawn settings remain unchanged. Replace the old JAR rather than installing both distributions.
