Fix JSDoc for trackClickHouseOperation function signature

[Copilot]

The JSDoc for trackClickHouseOperation documented a non-existent durationSeconds parameter instead of the actual status and startTime parameters.

Changes:

• Updated JSDoc to document actual parameters: status ('success' | 'error') and startTime (from performance.now())
• Removed incorrect durationSeconds parameter documentation
• Clarified that duration is computed internally, not passed as an argument

/**
 * Track a ClickHouse operation
 * @param operationType - Type of operation ('read' or 'write')
 * @param status - Operation status ('success' or 'error')
 * @param startTime - Operation start time from performance.now()
 */
export function trackClickHouseOperation(
    operationType: 'read' | 'write',
    status: 'success' | 'error',
    startTime: number,
): void {
    const durationSeconds = (performance.now() - startTime) / 1000;
    clickhouseOperations.labels(operationType, status).observe(durationSeconds);
}
