Duplicate/Copy-Paste Nodes in Workflow Builder

Problem:
When building workflows in, users often need to reuse the same action or a slightly modified version of an existing action multiple times within the same workflow or across different branches.

Currently, this requires manually adding a new node and re-configuring all its parameters (e.g., API keys, prompts, input/output variables, specific settings), which is time-consuming, repetitive, and prone to manual error.

Proposed Solution:
Introduce functionality to easily duplicate or copy and paste nodes within the workflow editor.
