💡 What: Replaced a manual O(N) regex loop (findNext) with an O(1) lookup of pre-computed match decorations from prosemirror-search's state using getMatchHighlights().
🎯 Why: Searching a large document with a common query like a space " " caused severe main thread blocking as countMatches() iterated over every single match in the document manually, despite the prosemirror-search plugin having already done the work.
📊 Impact: Match counting is now instantaneous regardless of the number of matches, eliminating a performance bottleneck on keystroke updates in the search panel.
🔬 Measurement: Search for a single space in a large document and note the UI no longer freezes during keystrokes in the find field.
