Adds `FastSafeIterableMapTest` to the common source set to verify the
correctness of the internal map implementation.

This ensures that basic operations function as expected and validates
safe iteration behavior. The tests cover edge cases such as removing
the current element, adding elements, and modifying the map during
nested iterations to prevent regression in the lifecycle runtime.

Adds the `androidx.collection` library as an implementation
dependency.

This enables the usage of optimized data structures, such as
`ScatterMap`.

Replaces the standard `LinkedHashMap` delegate with a custom intrusive
doubly-linked list backed by `MutableScatterMap`.

Previously, safe iteration required snapshotting keys into a list to
avoid `ConcurrentModificationException`. This change introduces "Ghost
Nodes"—removed entries that retain their pointers—allowing active
iterators to bridge back to the live list without copying data.

This results in zero-allocation iteration while maintaining safety when
observers modify the lifecycle during event dispatch.

Replaces platform-specific `expect`/`actual` implementations with a
single pure Kotlin implementation in the common source set.

This unifies behavior across all targets (Android, JVM, Native) and
removes the dependency on `androidx.arch.core` for the Android
source set, simplifying maintenance and ensuring consistent
iteration safety logic.

Previously, `BackHandler` and `PredictiveBackHandler` resolved both
Navigation and OnBackPressed owners unconditionally. This created
unnecessary composition dependencies and overhead.

This change optimizes the lookup by short-circuiting the resolution;
the legacy owner is now only observed if the primary Navigation owner
is missing.

Additionally, this fixes a correctness bug where the internal
dispatcher wrapper used `remember` without keys. The handler will now
correctly update if the parent dispatcher owner changes after the
initial composition.

Aligns the rotary snap over-scroll animation with the standard fling behavior to remove sluggishness.
Previously, `snapToTargetItem` used a low-stiffness spring and executed a secondary settling animation even at the boundary, delaying the bounce-back.

This change:
1. Uses the default (stiffer) spring spec during the first animation step when at the edge.
2. Skips the second animation step if still at the edge.

This ensures `fling(0f)` is triggered immediately, allowing the `OverscrollEffect` to produce a responsive bounce-back.
