Add the following counters to the healthcheck JSON response: - sessions: current active session count (from DB) - clients: current connected client count (from DB) - queuedLines: total entries in client output queues (from DB) - channels: current channel count (from DB) - connectionsSinceBoot: total client connections since server start - sessionsSinceBoot: total sessions created since server start - messagesSinceBoot: total PRIVMSG/NOTICE messages since server start Implementation: - New internal/stats package with atomic counters for boot-scoped metrics - New DB queries GetClientCount and GetQueueEntryCount - Healthcheck.Healthcheck() now accepts context for DB queries - Counter increments in session creation, registration, login, and messaging - Stats tracker wired via Uber fx dependency injection - Unit tests for stats package (100% coverage) and integration tests - README updated with full healthcheck response documentation closes #74
