Introduced a ProcessResult enum to standardize anti-injector message processing outcomes. Updated anti_injector.py to return ProcessResult values instead of booleans, and refactored bot.py to handle these results with improved logging and clearer control flow. This change improves code clarity and maintainability for anti-prompt injection logic.
Introduces a comprehensive anti-prompt injection system for LLMs, including rule-based and LLM-based detection, user ban/whitelist management, message shielding, and statistics tracking. Adds new modules under src/chat/antipromptinjector, integrates anti-injection checks into the message receive flow, updates configuration and database models, and provides test scripts. Also updates templates and logger aliases to support the new system.
