Block controls plugin for @atlaskit/editor-core

/**
 * Combines hover-driven and stored surface positions into one deduplicated list.
 * Shared by both the left and right surfaces: this is pure position bookkeeping with no
 * surface-specific behavior, so there's nothing to keep independent between them. What *is*
 * kept independent is each surface's own React tree (component lookup, measurement effects,
 * observers) — see block-controls-left-surfaces.tsx / block-controls-right-surfaces.tsx.
