/**
 * grafana_query_traces tool
 *
 * Run TraceQL queries against any Tempo datasource via Grafana's datasource proxy.
 * Supports two query types:
 *   - search: TraceQL expression → flat trace summaries
 *   - get: Trace ID → flattened span list with resolved attributes
 * Mirrors grafana_query_logs structure for consistency.
