Breaking Changes

elements

• Fix signal input getter behavior in custom elements.

Before this change, signal inputs in custom elements required function calls to access their values (elementRef.newInput()), while decorator inputs were accessed directly (elementRef.oldInput). This inconsistency caused confusion and typing difficulties.

The getter behavior has been standardized so signal inputs can now be accessed directly, matching the behavior of decorator inputs:

Before: - Decorator Input: elementRef.oldInput - Signal Input: elementRef.newInput()

After: - Decorator Input: elementRef.oldInput - Signal Input: elementRef.newInput
