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

BREAKING CHANGE: New releases require Java 25/Purpur 26.2 and use purpur-event-producer-<version>.jar. Runtime SpigotEventProducer identity, server UUID, SQLite outbox and CloudEvent delivery contracts remain unchanged. Replace the old JAR rather than installing both distributions.

-A Spigot 26.2 plugin that records Minecraft activity as CloudEvents 1.0, persists it in a local SQLite outbox, and sends newline-delimited batches to `game-ingest-server`.

 ## Requirements
 
-- Spigot 26.2
-- Java 17 or newer
+- Purpur 26.2 build 2618
+- Java 25
 - Network access to the ingest endpoint
 
+The repository, checkout and new artifacts use `purpur-event-producer`. Runtime `SpigotEventProducer`, Java entrypoint/packages, existing configuration/server UUID and `plugins/SpigotEventProducer/event-outbox.sqlite3` remain unchanged, as do CloudEvent types/source/payloads and delivery semantics. The SQLite driver stays bundled. Replace the old JAR rather than installing both distributions. Old tags/assets remain available; new releases no longer support Java 17.

 ## Build and install
 
 ```bash
-./gradlew clean test jar
-cp build/libs/spigot-event-producer-0.1.0-SNAPSHOT.jar /path/to/server/plugins/
+./gradlew clean check jar
+cp build/libs/purpur-event-producer-0.1.0-SNAPSHOT.jar /path/to/server/plugins/
 ```
 
 Start the Minecraft server once to create `plugins/SpigotEventProducer/config.yml`. Set a meaningful, stable `server-name`. When `server-id` is empty, the plugin generates and persists a UUID. Do not reuse that generated UUID on another server.

 Private-message events recognize `/msg`, `/message`, `/tell`, `/w`, `/whisper`, `/pm`, `/reply`, and `/r`, including namespaced variants such as `/minecraft:tell`. Explicit commands contain the destination token. Reply commands set `reply: true` and omit the recipient so downstream processing can infer it from earlier ordered events. The event also reports whether the command was cancelled.
 
-Spigot has no universal private-message event. Commands implemented with unrelated aliases or entirely custom plugin logic will not be recognized until their syntax is added. A recognized command event reports observation of the command, not guaranteed delivery to its recipient.
