- aiomysql → asyncmy on both sides of the URL/import (faster, maintained).
- Pool sizing now reads DECNET_DB_POOL_SIZE / MAX_OVERFLOW / RECYCLE /
PRE_PING for both SQLite and MySQL engines so stress runs can bump
without code edits.
- MySQL initialize() now wraps schema DDL in a GET_LOCK advisory lock so
concurrent uvicorn workers racing create_all() don't hit 'Table was
skipped since its definition is being modified by concurrent DDL'.
- sqlite & mysql repo get_log_histogram use the shared _session() helper
instead of session_factory() for consistency with the rest of the repo.
- SSE stream_events docstring updated to asyncmy.
