refactoring - extract generateTaskSpec (#1074)

## Description

Moved the `generateTaskSpec` function from `GhostNode.tsx` to a dedicated utility file at `src/utils/nodes/generateTaskSpec.ts` to improve code organization and reusability. This function creates a TaskSpec object with default position annotations from a ComponentReference.
