/**
 * Hook that detects and tracks changes in device pixel ratio (DPR).
 * Returns both the current DPR and a version counter for forcing remounts.
 * This is crucial for proper canvas rendering on high-DPI displays.
 *
 * The hook listens for changes in DPR which can occur when:
 * - Moving a window between displays with different pixel densities
 * - Fullscreening on a different monitor
 * - Browser zoom changes (Cmd/Ctrl +/-)
 *
 * @returns {{ dpr: number, version: number }} Current DPR and version counter
