Changed forward iteration to backward iteration when checking for word characters. This optimization reduces unnecessary iterations by checking characters from the cursor position backward instead of iterating through all characters from the start. The functionality remains identical, but the performance is improved for cases where the cursor is far from the beginning of the line.

This PR optimizes the loop in
deleteWordLeftthat checks for word characters. Instead of iterating forward through all characters from 0 to cursor position, it now iterates backward from the cursor. This is more efficient since we can exit early when finding a word character.The functionality remains unchanged - just the iteration direction.
