/**
 * `plugin_logs` table — structured log storage for plugin workers.
 *
 * Each row stores a single log entry emitted by a plugin worker via
 * `ctx.logger.info(...)` etc. Logs are queryable by plugin, level, and
 * time range to support the operator logs panel and debugging workflows.
 *
 * Rows are inserted by the host when handling `log` notifications from
 * the worker process. A capped retention policy can be applied via
 * periodic cleanup (e.g. delete rows older than 7 days).
