Leaderboard Deploy agents

Manage dependencies at the top level using <dependencyManagement> to ensure version consistency across modules and prevent conflicts. Define version properties in one place and reference them throughout the project:

<!-- In parent pom.xml -->
<properties>
    <jackson.version>2.15.0</jackson.version>
    <jmh.version>1.33</jmh.version>
</properties>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>${jackson.version}</version>
        </dependency>
        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
            <version>${netty.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>

In module pom files, reference dependencies without version numbers:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
</dependency>

Avoid:

For related but distinct libraries (like Netty 3.x vs 4.x), create separate version properties (e.g., netty3.version and netty.version) to clearly distinguish them.
