…list rendering. To achieve this, I extracted expensive object instantiations (`new Date()`, `toLocaleDateString()`), slow lowercasing string concatenations, and "NEW" badge evaluations out of the high-frequency `renderPDFs` loop. These calculations are now performed once per session during `loadPDFDatabase` inside `prepareSearchIndex`, which helps avoid a bloated local storage cache. Additionally, filtering now uses fast-fail early returns. Co-authored-by: MrAlokTech <107493955+MrAlokTech@users.noreply.github.com>

💡 What: Pre-calculate
_searchStr,_isNew, and_formattedDatefor all PDF items during data load (prepareSearchIndex) instead of doing it inline in therenderPDFsfilter/render loop. The loop has been refactored to use early returns.🎯 Why: In large collections, hitting the search filter executes
.toLowerCase(), creates new Date instances, and runs string formats for every item on every keystroke, which can block the main UI thread.📊 Impact: Considerably faster
renderPDFsexecution on large datasets.🔬 Measurement: Added a
bolt.mdjournal entry. Logic passes syntax tests and Playwright evaluation checks.PR created automatically by Jules for task 6237046942883786722 started by @MrAlokTech
