Database connectivity and query profiling support for the `dataprof` workspace.
This crate owns connector configuration and traits, PostgreSQL, MySQL, and

sampling, retries, and batched streaming helpers. It does not own generic
profile metrics or Python bindings.
## Public surface

`create_connector`, `analyze_database`, and the backend connector types.
## Features
- `postgres`: PostgreSQL support.
- `mysql`: MySQL/MariaDB support.
- `sqlite`: SQLite support.
- `all-db`: all three backends.
The default feature set is empty.
