Implement Value Caching and Diffing for Optimized Change Detection

[faizanu94]

This pull request introduces value caching and diffing mechanisms to optimize change detection. By caching previous values and diffing them against current values, we ensure that only the property that has changed is passed to the callback function as discussed in #1

Changes

• Added a value caching system to store previous state values
• Implemented a diffing algorithm to efficiently compare current values against cached values
• Modified callback functions to receive only the properties that have changed, based on the diffing results
