PreferStableKeysInLazyColumn [rule] v0.1.0

LazyColumn, LazyRow, and LazyVerticalGrid use the key parameter on each item to identify it across recompositions. Without a key, Compose falls back to position — which means inserting at the head re-keys every following item, animations break, scroll position drifts, and per-item state (like a remembered expand flag) jumps to the wrong row. Pass a key = { item -> item.id } whose value is stable for the lifetime of that item.

Checks

• Every items(...) and itemsIndexed(...) call has an explicit key = { ... } lambda when the list is mutable or paginated.
• Keys are unique within the list and stable across reorderings (typically a primary-key id from the data model).
• Keys are NOT the index, NOT the hashCode of the whole item, NOT a randomly generated value at composition time.
• Keys are types Compose treats as Saveable (Int, Long, String, parcelable) so list state survives configuration change.
