/**
 * The `Injector` abstract class provides a framework for dependency injection,
 * allowing the resolution and injection of parameters, functions, and constructors.
 * It supports synchronous and asynchronous resolution of dependencies, as well as
 * advanced features like nested property resolution and fallback mechanisms.
 *
 * Key Features:
 * - Resolves parameters and injects them into functions or constructors.
 * - Supports both synchronous and asynchronous dependency resolution.
 * - Handles nested property resolution and fallback mechanisms for unresolved keys.
 * - Provides utilities for merging arguments, collecting parameter maps, and applying them.
 * - Allows injection of new instances of constructors or asynchronous functions.
 *
 * Usage:
 * Extend this class to implement custom dependency injection logic by overriding
 * the abstract methods `resolve`, `onResolve`, and `inspect`.
 *
 * Example:
 * ```typescript
 * class MyInjector extends Injector {
 *     resolve<T>(param: Resolvable): T {
 *         // Custom resolution logic
 *     }
 *     onResolve<T>(name: Resolvable): PromiseLike<T> {
 *         // Custom asynchronous resolution logic
 *     }
 *     inspect(): void {
 *         // Custom inspection logic
 *     }
 * }
 * ```
