Contributor guide

Research direction
Investigate the query execution pipeline to find where logging decisions are made. Use the existing logging infrastructure (likely the `tracing` crate) and understand how to pass per query configuration to the relevant modules. Look at how the `SET` command is parsed and executed, and then propagate the log level to the query execution context.
