/**

 * Chromosome mutation handler that adds new connections to NEAT (NeuroEvolution of Augmenting Topologies) neural networks.

 * <p>NeatChromosomeAddConnection implements the add-connection structural mutation for NEAT chromosomes,

 * which increases network connectivity by creating new weighted links between existing nodes. This mutation

 * is essential for NEAT's ability to explore different network topologies and discover optimal connectivity patterns.

 * <p>Add-connection mutation process:

 * <ol>

 * <li><strong>Node selection</strong>: Randomly select source and target nodes from all available nodes</li>

 * <li><strong>Validity checking</strong>: Ensure the connection doesn't violate network constraints</li>

 * <li><strong>Duplicate prevention</strong>: Verify the connection doesn't already exist</li>

 * <li><strong>Innovation assignment</strong>: Assign unique innovation number via InnovationManager</li>

 * <li><strong>Weight initialization</strong>: Set random weight within chromosome bounds</li>

 * <li><strong>Connection creation</strong>: Add enabled connection to the chromosome</li>

 * </ol>

 * <p>Connection constraints:

 * <ul>

 * <li><strong>No self-connections</strong>: Source and target nodes must be different</li>

 * <li><strong>No duplicate connections</strong>: Connection between same nodes cannot already exist</li>

 * <li><strong>Feed-forward topology</strong>: Output nodes cannot be sources, input nodes cannot be targets</li>

 * <li><strong>Valid node references</strong>: Both nodes must exist in the network</li>

 * </ul>

 * <p>Node selection strategy:

 * <ul>

 * <li><strong>Available nodes</strong>: All input, output, and hidden nodes are potential connection endpoints</li>

 * <li><strong>Dynamic range</strong>: Node range adapts to include any hidden nodes created by add-node mutations</li>

 * <li><strong>Uniform selection</strong>: All valid nodes have equal probability of being selected</li>

 * <li><strong>Constraint filtering</strong>: Invalid connections are rejected and no mutation occurs</li>

 * </ul>

 * <p>Common usage patterns:

 * <pre>{@code

 * // Create add-connection mutation handler

 * RandomGenerator randomGen = RandomGenerator.getDefault();

 * InnovationManager innovationManager = new InnovationManager();

 * NeatChromosomeAddConnection handler = new NeatChromosomeAddConnection(

 *     randomGen, innovationManager

 * );

 * // Check if handler can process mutation

 * AddConnection mutationPolicy = AddConnection.of(0.1);

 * NeatChromosomeSpec chromosomeSpec = NeatChromosomeSpec.of(3, 2, -1.0f, 1.0f);

 * boolean canHandle = handler.canHandle(mutationPolicy, chromosomeSpec);

 * // Apply mutation to chromosome

 * NeatChromosome originalChromosome = // ... existing chromosome

 * NeatChromosome mutatedChromosome = handler.mutate(mutationPolicy, originalChromosome);

 * // Result: chromosome may have one additional connection (if valid connection found)

 * }</pre>

 * <p>Integration with NEAT algorithm:

 * <ul>

 * <li><strong>Innovation tracking</strong>: Uses InnovationManager for consistent innovation number assignment</li>

 * <li><strong>Population consistency</strong>: Same connection types get same innovation numbers across population</li>

 * <li><strong>Genetic alignment</strong>: Innovation numbers enable proper crossover alignment</li>

 * <li><strong>Structural diversity</strong>: Increases topological diversity in the population</li>

 * </ul>

 * <p>Weight initialization:

 * <ul>

 * <li><strong>Random weights</strong>: New connections get random weights within chromosome bounds</li>

 * <li><strong>Uniform distribution</strong>: Weights uniformly distributed between min and max values</li>

 * <li><strong>Immediate activation</strong>: New connections are enabled and immediately affect network behavior</li>

 * <li><strong>Bounded values</strong>: Weights respect chromosome's min/max weight constraints</li>

 * </ul>

 * <p>Performance considerations:

 * <ul>

 * <li><strong>Efficient validation</strong>: Fast checks for connection existence and validity</li>

 * <li><strong>Innovation caching</strong>: Leverages InnovationManager's O(1) innovation lookup</li>

 * <li><strong>Memory efficiency</strong>: Minimal allocation during mutation</li>

 * <li><strong>Failed mutation handling</strong>: Gracefully handles cases where no valid connection can be added</li>

 * </ul>
