Module manager 

Database connection manager for SQLite tools

Provides a singleton pattern for managing multiple database connections across tool invocations.

Test Isolation

For test isolation, create local DatabaseManager instances instead of using the global DATABASE_MANAGER. Each instance has its own connection pool and default database setting. Tool tests that use the global should call close_all() in cleanup to reset state.
