What is the current behavior?

The current behavior of the Store Status Plugin involves tracking the loading and modification status of a store.

We've recognized a need for a clearer distinction between modification and initialization. In numerous scenarios, it's essential to determine if a store has been initialized, especially after a backend call or side effect. The existing isModified function is not ideal for this purpose.

Additionally, the naming of isModified, has been identified as potentially misleading. While isModified is intended to indicate whether the store has been modified, it may be interpreted as an ongoing process.

What is the new behavior?

The initialized function determines if a store has been initialized, making it particularly useful after backend calls or side effects.

isModified has been renamed to modified. These aligns well with the new initialized signal and aims to enhance code readability in conditionals.

Additionally, the deprecated markAsUnmodified function is replaced with the more comprehensive resetStoreStatus, allowing for manual resetting of both initialization and modification statuses.

Does this PR introduce a breaking change?

[ ] Yes
[x] No

Other information

• Rename setUnmodifiedStatus to setInitializedStatus in effects.
• Introduce initialized() function to track store initialization status.
• Introduce resetStoreStatus() to manually reset store status.

Deprecation:

• Deprecate isModified(), use modified() instead.
• Deprecate markAsUnmodified(), use resetStoreStatus() instead.
