fix: removing drawing when no circle or rectangle is drawn

[zytact]

Summary by CodeRabbit

• Refactor
  • Improved drawing interactions by updating the logic to record drawing history only when a valid starting point is provided, ensuring that shape rendering (e.g., for rectangles and circles) occurs only when appropriate, which may enhance responsiveness and prevent unintended state updates.

Walkthrough

The changes update the InfiniteCanvas component by modifying the conditions for adding history during the interaction state reset. History for rectangle and circle drawing modes is now only recorded if a valid startPoint exists. Additionally, startPoint is added to the dependency array of the resetInteractionStates function, ensuring that any update to startPoint triggers a re-evaluation of the effect.

Poem

I'm a rabbit, hopping with glee,
Coding changes for shapes, quick as can be.
A startPoint now guides the drawing way,
Recording history only when in play.
With every hop, my code springs to life,
Celebrating the tweaks with a carrot high-five!

1511-1516: Good fix: Preventing history addition for empty rectangle drawings.

Adding this condition ensures that history is only recorded when the user has actually started drawing a rectangle. This prevents cluttering the history with empty drawing states.

However, the comment "Add history even if no startPoint to ensure proper state update" seems contradictory to the change you've made, as you're now specifically checking for startPoint. Consider updating this comment to reflect the actual behavior.

1517-1521: Good fix: Preventing history addition for empty circle drawings.

Similar to the rectangle fix, this ensures history is only recorded when the user has actually started drawing a circle. This is a good improvement for user experience.

1534-1534: Correct dependency addition for the useCallback hook.

Adding startPoint to the dependency array is necessary since the function now uses this value in its conditional logic. This ensures the callback is properly recreated when the startPoint changes.
