feat: enhance Abstraction class with implementation and decorator creation methods

[adrians5j]

This Pull Request expands the Abstraction class in Abstraction.ts to support creating implementations, decorators, and composites with metadata management.

Added new methods:

• createImplementation, createDecorator, and createComposite for working with abstractions.
• Introduced metadata handling for dependencies and additional attributes like IS_DECORATOR and IS_COMPOSITE.
• Enhanced the utility and customization capabilities of the Abstraction class.

Token uniqueness:

• use Symbol(name) to make each abstraction unique, even if using the same name
