/**
 * ESLint rule to prevent optional logger parameters in class constructors
 *
 * This rule enforces that logger parameters in class constructors must be required,
 * not optional. Logger is a critical dependency that should always be provided
 * for proper debugging and monitoring.
 *
 * @example
 * // Bad
 * class MyService {
 *   constructor(config: Config, logger?: IDextoLogger) {}
 * }
 *
 * // Good
 * class MyService {
 *   constructor(config: Config, logger: IDextoLogger) {}
 * }
