Hot Reload

`RuleEngine` is immutable. Use `RuleEngineRef` when rules are stored in a JSON file and should be reloaded without restarting the application.

JAVA

RuleEngineRef<GameContext> rules = RuleEngineRef.fromJsonPath(
        RuleEngine.builder(GameContext.class)
                .conditions(GameRules::condition)
                .actions(GameRules::action),
        Path.of("rules.json"));

Fire the current snapshot:

JAVA

rules.fire(GameTrigger.PLAYER_JOINED, context);

Reload only if the file changed:

JAVA

boolean changed = rules.reloadIfChanged();

If reading or compiling the new file fails, the previous valid engine snapshot remains active.
