Callback registered by every RenderSliverTree attached to a TreeController.
Invoked from TreeController.moveNode (and any future animated mutation)
to ask the render object to snapshot current painted offsets BEFORE the
mutation so the next performLayout can install a FLIP slide from
baseline to post-mutation.
Returning true means "the host is participating in this slide cycle",
either it staged a fresh baseline now, or a prior call this frame already
staged one and the host is honoring the first-wins policy. Returning
false indicates the host cannot participate at all (not yet laid out,
detached, etc.).
Internal contract: this interface is part of the sliver-render-object
staging protocol. External callers should not implement or depend on it.
One implementer, RenderSliverTree, which registers ITSELF so the
registry can also read render-side CONFIG (the sticky depth) without a
second back-channel (M20).
