/**
 * Port Coordinate Store (Svelte 5 Runes)
 *
 * General-purpose store that maintains absolute canvas-space coordinates
 * for all port handles in the workflow. Built from SvelteFlow's internal
 * handle bounds data combined with FlowDrop port metadata.
 *
 * Primary consumers:
 * - Proximity connect (port-to-port distance instead of node center distance)
 *
 * Coordinates are derived from SvelteFlow's InternalNode.internals.handleBounds
 * which SvelteFlow already maintains for all node types. This avoids replicating
 * CSS positioning logic and stays automatically accurate.
