-Step 7: Allow uploading .txt + .pdf + .html files from the Admin panel (then auto-reindex).
+Step 8: Add generative mode controls and pass them to Evo synthesis.

-- Rebuild index and clear the cached searcher.
+New (Objective):
+- Radio to choose "Extractive (safe)" vs "Generative (Evo)".
+- Sliders for temperature and max tokens.
