fix: avoid invalid transforms in repeat_array when count is 1

[Sanketjadhav31]

Summary

While looking through the repeat nodes, I noticed that repeat_array allows count = 1, but the calculation uses (count - 1) as a denominator.

When count is 1, this results in a zero denominator and can produce invalid transform values during the angle and translation calculations.

This change guards against that edge case by ensuring the denominator is at least 1.

Changes

• Prevent division by zero when count = 1
• Keep existing behavior unchanged for count >= 2

Testing

Reasoned through the count = 1 execution path and verified that the denominator can no longer become zero.

Code Review

This pull request modifies the repeat_array function in repeat_nodes.rs to ensure that the total calculation has a minimum value of 1.0 by using .max(1) on count - 1. This prevents potential division by zero or invalid calculations when count is 1. There are no review comments to evaluate.
