Replaced promise chaining with async/await syntax to improve clarity and handle asynchronous logic. Added JSDoc comments to document method parameters and behavior. Updated logic to conditionally preserve cooked HTML and ensure the topic reference is correctly updated.
Updated property assignment logic in `store` to only update changed values, preventing unnecessary rerenders in Glimmer.
Removed unnecessary resolved promise and streamlined the return behavior for cases where `postId` is not provided.
Introduced `untrack` and `deepEqual` to optimize property comparisons. Updated logic to batch property updates, ensuring rerenders are only triggered when necessary.
Prevents max call stack errors in the comparison logic by replacing `deepEqual` with a strict equality check (`===`).
