Fix: upload actual app.py content (was literal string from previous upload)

Replace piiranha-v1 CPU fallback with GLiNER-PII (zero-shot, 60+ entity types, F1=81%)

Upgrade CPU model: piiranha-v1 → GLiNER-PII (zero-shot, 60+ types, F1=81%)

Add transformers back for CPU fallback model

Dual-mode: openai/privacy-filter on ZeroGPU, piiranha-v1 CPU fallback

Update README.md: enable ZeroGPU for openai/privacy-filter model

Switch PII detection model from piiranha NER to openai/privacy-filter (1.4B MoE)

Update requirements for openai/privacy-filter model

Fix: remove pyaudioop from requirements

Fix: update sdk_version to 5.25.0 for Python 3.13 compatibility, remove pyaudioop

Fix: add pyaudioop for Python 3.13 compatibility with Gradio
