/**
 * useVisibleNodes returns row indices visible in the current viewport through multi-stage culling.
 * Combines depth buckets, horizontal bounds checking, and size filtering to
 * minimize rendered nodes from potentially 100K+ rows to ~hundreds.
 *
 * We use depth buckets to only iterate through the rows that are visible in the viewport vertically.
 * After that we use horizontal bounds checking to only iterate through the rows that are visible in the viewport horizontally.
 * Finally we use size filtering to only iterate through the rows that are visible in the viewport by size.
 *
 * Critical for maintaining 60fps performance on large flamegraphs where
 * rendering all nodes would freeze the browser.
