Canvas Navigation & Visualization Improvements

Implement a minimap on the canvas to provide an overview and enable rapid navigation across complex flows.

Allow users to move around the canvas without clicking, such as by supporting trackpad gestures (e.g., two-finger scroll), to make panning more intuitive.

Add a search function within flow diagrams to help users quickly find specific nodes, prompts, or components.

Create a set of flow builder settings that permit toggling various features on or off, giving users more control over their workspace.
