/**
 * grafana_update_dashboard tool
 *
 * Five operations in one tool:
 *   - add_panel: Add a new panel with auto-layout + query validation
 *   - remove_panel: Remove a panel by ID or title
 *   - update_panel: Merge updates into an existing panel + query validation
 *   - update_metadata: Change title, description, tags, time range, refresh
 *   - delete: Permanently remove a dashboard
 *
 * Uses the same POST /api/dashboards/db endpoint as create-dashboard,
 * but preserves dashboard.id and version for update semantics.
 *
 * Query validation: When adding or updating panel targets, PromQL expressions
 * are dry-run against Grafana. The panel is always saved regardless — validation
 * is informational, included as a queryValidation object in the response.
