Rag run #155

No description provided.

…ved input data handling for tests - Replaced structuredClone and JSON methods with a new smartClone function that deep-clones plain objects and arrays while preserving class instances by reference. - quick versions of tasks as functions now pass input to run not the constructor which means no defaults and cloning

…ng additional input properties.

Pull request overview

This PR introduces a fundamental architectural change to how tasks are instantiated and executed, with the title "Rag run" suggesting this may be related to Retrieval-Augmented Generation workflows that require passing non-serializable objects like repositories.

Key changes:

Task constructors now receive empty type-asserted objects instead of actual input data
The run() method now accepts input as a parameter instead of using constructor-provided input
New smartClone method replaces structuredClone to handle class instances and TypedArrays by reference
Removed undefined value checks in setInput and addInput for additional properties

The smartClone implementation has a potential issue with circular references in plain objects and arrays. While class instances are passed by reference (avoiding circular reference issues), if a plain object or array contains circular references, this method will cause infinite recursion and stack overflow. Consider adding circular reference detection or documenting this limitation clearly.
