perf: optimize container lookup with early exit

eplaced an inefficient forEach loop with the find() method in the render() function's container lookup logic, enabling early exit when a matching container is found.

Type of Change Bug fix (performance optimization) New feature Breaking change Documentation update The Problem In src/pure.js lines 286-293, when reusing an existing container, the code used forEach to search through mountedRootEntries:

javascript mountedRootEntries.forEach(rootEntry => { if (rootEntry.container === container) { root = rootEntry.root } }) The forEach method continues iterating through all entries even after finding the matching container. This is inefficient because:

It performs unnecessary iterations after the match is found Performance degrades as more containers are mounted The code doesn't communicate the intent to find a single entry The Solution Replaced forEach with the find() method which stops iteration immediately upon finding a match:

javascript const rootEntry = mountedRootEntries.find( rootEntry => rootEntry.container === container, ) if (rootEntry) { root = rootEntry.root } This change:

⚡ Stops searching immediately when a match is found (early exit optimization) Improves performance, especially with multiple mounted containers Makes the code intent clearer - we're looking for one specific entry ✅ Uses a more idiomatic JavaScript pattern
