Implement a new statistics module that records export operations per month,
including total revenue, item count, and average order value. The module
aggregates data from the orders and shipments tables, grouping results by
calendar month for reporting purposes.
Implement a new logging utility with configurable verbosity levels and integrate a rant_history data structure to persist user interaction records across sessions. The logging module includes timestamped entries with severity tags, while rant_history stores chronological entries with metadata for future analysis and replay features.
