/**
 * Grafana Lens plugin configuration types.
 *
 * These mirror the JSON Schema in openclaw.plugin.json but provide
 * TypeScript types for use within the extension code.
 *
 * Config precedence: explicit plugin config > environment variables > defaults.
 * Env vars follow Grafana community conventions (GRAFANA_URL, GRAFANA_SERVICE_ACCOUNT_TOKEN)
 * and OpenTelemetry conventions (OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_HEADERS).
 *
 * Supports two grafana config formats:
 *   1. Legacy single instance:  { url, apiKey, orgId }
 *   2. Named instances:         { instances: [{ name, url, apiKey, orgId }], default? }
 * Both normalize to the same internal shape: { instances: Record<name, config>, defaultInstance }.
