Split the anti-prompt-injector module into core, processors, management, and decision submodules for better maintainability and separation of concerns. Moved and refactored detection, shielding, statistics, user ban, message processing, and counter-attack logic into dedicated files. Updated imports and initialization in __init__.py and anti_injector.py to use the new structure. No functional changes to detection logic, but code organization is significantly improved.
Added MaiBot-dev.code-workspace to .gitignore to prevent it from being tracked. Changed the working directory in the Dockerfile from /MaiMBot to /mmc for consistency or project structure update.
