-/**
- * Public API for Paper plugins that want to attach the access widener agent.
- *
- * <h2>Usage</h2>
- * Call {@link #ensureAttached(Path)} from your plugin's {@code onLoad()} method
- * (not {@code onEnable()} — onLoad fires before classes start loading):
- *
- * <pre>{@code
- * public class MyPlugin extends JavaPlugin {
- *     @Override
- *     public void onLoad() {
- *         try {
- *             AccessWidenerAttacher.ensureAttached(getDataFolder());
- *         } catch (Exception e) {
- *             getSLF4JLogger().error("Failed to attach access widener agent", e);
- *         }
- *     }
- * }
- * }</pre>
- *
- * <h2>Resource file</h2>
- * Drop a {@code plugin.accesswidener} file in your plugin's resources:
- *
- * <pre>
- *   accessWidener v2 named
- *
- *   accessible method net/minecraft/server/level/ServerPlayer getStats ()V
- *   mutable    field  net/minecraft/world/entity/Entity id I
- * </pre>
- *
- * The agent discovers it automatically via your plugin's ClassLoader.
