/**
 * Generates strength-related analytics from stored activities and prints them as tables or JSON.
 *
 * Executes aggregated queries against the initialized activities database and outputs:
 * - efficiency metrics per sport over a recent window,
 * - summaries of long easy (aerobic) sessions,
 * - most recent session date and counts per sport for the last year,
 * - historical distance/time peaks over a configurable number of years.
 *
 * @param args - Options that control query windows and output format. Recognized fields include
 *   `months`, `longMonths`, `easyHrMax`, `longMinutes`, `years` (numeric thresholds with defaults)
 *   and `json` (when true, emits a combined JSON object instead of formatted tables).
