This commit refactors the handling of ALLOWED_ROOT_DIRECTORY by removing legacy support for ALLOWED_PROJECT_DIRS and simplifying the security logic. Key changes include:
- Removed deprecated ALLOWED_PROJECT_DIRS references from .env.example and security.ts.
- Updated initAllowedPaths() to focus solely on ALLOWED_ROOT_DIRECTORY and DATA_DIR.
- Enhanced logging for ALLOWED_ROOT_DIRECTORY configuration status.
- Adjusted route handlers to utilize the new workspace directory logic.
- Introduced a centralized storage module for localStorage operations to improve consistency and error handling.
These changes aim to enhance security and maintainability by consolidating directory management into a single variable.
Tests: All unit tests passing.
