Module db 

Database access layer.

Provides connection pool initialization, migration execution, and query helpers for the three supported backends: SQLite, PostgreSQL, and MariaDB.

The shared connection pool type Db is a runtime-dispatch AnyPool that routes queries to the configured backend. All write transactions on SQLite should go through begin_write rather than pool.begin() to avoid SQLITE_BUSY_SNAPSHOT in WAL mode.
