🎯 What: Fixed an uninitialized variable stateChanged in the ABounce constructor.
⚠️ Risk: An uninitialized variable can lead to undefined behavior. In this case, risingEdge() and fallingEdge() might return incorrect true values immediately after the object is created if the memory location happens to contain a non-zero value, potentially triggering unintended actions in the calling code.
🛡️ Solution: Explicitly initialized stateChanged to 0 in the constructor to ensure a predictable state.


PR created automatically by Jules for task 1284980525617499951 started by @prestalab

🎯 What:
Initialize the `stateChanged` member variable in the ABounce constructor.

⚠️ Risk:
The `stateChanged` variable was previously uninitialized, leading to undefined behavior. This could cause `risingEdge()` or `fallingEdge()` to return true incorrectly upon object creation if the memory contains non-zero data, potentially triggering erroneous logic in applications using this library.

🛡️ Solution:
Added `stateChanged = 0;` to the ABounce constructor in ABounce.cpp to ensure it starts in a known state.
