Locks the drawer side inferred at the start of a continuous drag so reversing across neutral no longer activates the opposite action pane mid-gesture. Adds a resisted rubber-band movement while the user pulls toward the non-inferred side, then resets the intent only after the drag settles back to neutral. Covers the behavior with LTR, RTL, neutral-reset, and already-open-pane regression tests. This is the same UX class as upstream issue letsar#311.

Adds the updated after-capture GIF used in upstream PR letsar#547 so the embedded media shows the overscrolled release settling back to neutral with animation instead of appearing to jump.

Summary
This locks action-pane intent for a continuous interactive drag so the slidable cannot switch to the opposite pane after crossing neutral in the same gesture.
The controller now infers the pane direction once per drag, or reuses the already-open pane when a drag begins from an open state.
If the user reverses past neutral before releasing, the slidable keeps the originally inferred pane active and shows only a small resisted rubber-band offset.
If the user releases from that overscrolled state, the child animates back to neutral instead of jumping.
Programmatic open and close flows are unchanged, and there are no public API changes.
