PhantomClipRole enum

Role of a phantom-anchored sliding row, selecting how RenderSliverTree._resolvePhantomAnchorBounds computes its clip.

The clip helper is a chokepoint with two callers whose intent is OPPOSITE, so the rule must branch on the role:

• entry: a previously-hidden node reparented INTO view that must EMERGE past its anchor. The legacy half-plane clip applies (the anchor occludes the START of the trajectory; as the row slides away the half-plane reveals progressively more of it). There is NO header repaint over this row, so the band/far-overhang rule MUST NOT reach it.
• exit: a row purged from visibleNodes sliding INTO a collapsed header to DISAPPEAR. The destination band is repainted on top by Pass A.7 / Pass B, so the clip bounds the FAR overhang of a tall card past the destination header's PAINTED band.
