/**
 * Builds a PluginRegistry from an array of plugins.
 *
 * This function:
 * 1. Validates each plugin individually (structure, codecs, operators, generators)
 * 2. Validates operator conflicts (between plugins and with built-in operators)
 * 3. Validates dependencies (all declared dependencies must exist)
 * 4. Merges codecs (append in registration order)
 * 5. Merges operators into a Map (O(1) lookup)
 * 6. Merges ID generators into a Map (O(1) lookup)
 * 7. Merges global hooks (concatenate arrays in registration order)
 *
 * If plugins is undefined or empty, returns an empty registry.
 *
 * @param plugins - Array of plugins to validate and merge (optional)
 * @returns Effect<PluginRegistry, PluginError> - The merged registry or validation error
