Extracts the expensive `.toLowerCase()` operations and `Date` formatting out of the `renderPDFs` and `createPDFCard` rendering loops. Adds `prepareSearchIndex` to cache these on items during initialization to improve UI responsiveness on search keystrokes. Co-authored-by: MrAlokTech <107493955+MrAlokTech@users.noreply.github.com>

💡 What:
Extracted string conversions (
.toLowerCase()) andDateinstantiations from therenderPDFs()andcreatePDFCard()loops, moving them to a newprepareSearchIndex()function that runs once when data is fetched.🎯 Why:
The search functionality re-renders the PDF list on every keystroke. For large lists, repeatedly instantiating
Dateobjects and executing multiple string conversions inside the render/filter loop causes significant main thread overhead, resulting in UI jank and unresponsiveness.📊 Impact:
Eliminates hundreds of redundant operations per keystroke on large datasets.
Dateinstantiations and.toLowerCase()string operations are reduced to a single O(n) pass during data initialization, resulting in a measurable performance increase and smoother UI.🔬 Measurement:
Run a Playwright script with an active
http.serverto confirmprepareSearchIndexcompletes correctly and filters items during search efficiently. Search UI responds correctly and faster.PR created automatically by Jules for task 1672653164283399281 started by @MrAlokTech
