fix: expose @spaces.GPU functions in app.py for ZeroGPU detection, drop bitsandbytes

feat: sync all features from local-guide — BRIEF synthesis, REVIEW, weekly thread, unified lm.py, new frontend build

fix: lower similarity threshold to 0.50 for MiniLM, backfill on every restart

fix: use BitsAndBytesConfig for 4-bit quant, add torchvision for vision model
