AI-Powered Discord Bot

• Privacy controls: optional encrypted in‑memory context cache (opt‑in, 2h TTL); no message content persisted to disk.
• Multimodal pipeline: GPT‑4o + Gemini Vision with PDF text extraction; supports files up to 50MB.
• Async processing: aiohttp downloads, Pillow image prep, PyPDF2 parsing; resilient error handling and rate‑limit handling.
• Language detection: English, Hinglish, and Romanized Hindi with context‑aware prompts.
• Discord delivery: automatic 2000‑char message splitting; typing indicators and helpful /help, /clear commands.
• Modes: sarcasm and personality styles; file‑only analysis defaults to GPT when no command provided.
• Privacy commands: `/privacy`, `/privacy allow`, `/privacy deny`, `/privacy clear` (only consent flags are persisted).
• Strict mode: anonymizes participant names in prompts to reduce PII exposure.
• Attachment rules: one attachment per message with automatic type detection (image, PDF, text).
• Debug mode: optional verbose logging for regular and sarcasm flows to aid troubleshooting.
• Deploy‑ready: Railway configuration and `.env` driven keys; sensible defaults and quick start.
