/**
 * Generate a coverage summary from a detailed coverage report
 *
 * The summary includes coverage metrics for each file and a total across all files.
 * For each category (lines, functions, branches), it calculates:
 * - total: number of items that could be covered
 * - covered: number of items that were actually covered
 * - pct: percentage of covered items (100% if total is 0)
 *
 * @param report - Detailed coverage report containing data for each file
 * @returns Coverage summary with per-file metrics and totals
 *
 * @example
 * ```typescript
 * const report = loadAndParse("lcov.info");
 * const summary = generateSummary(report);
 * console.log(summary.total.lines.pct); // Overall line coverage percentage
 * ```
