 * Filter a record of MCP server configs by managed policy (allowedMcpServers /

 * control message (print.ts, SDK V2 Query.setMcpServers()).
 *
 * SDK-type servers are exempt — they are SDK-managed transport placeholders,

 * mcp_tool_call. URL/command-based allowlist entries are meaningless for them
 * (no url, no command), and gating by name would silently drop them during
 * installPluginsAndApplyMcpInBackground's sdkMcpConfigs carry-forward.
 *
 * The generic has no type constraint because the two callsites use different
 * config type families: main.tsx uses ScopedMcpServerConfig (service type,
 * args: string[] required), print.ts uses McpServerConfigForProcessTransport
 * (SDK wire type, args?: string[] optional). Both are structurally compatible
 * with what isMcpServerAllowedByPolicy actually reads (type/url/command/args)
 * — the policy check only reads, never requires any field to be present.
 * The `as McpServerConfig` widening is safe for that reason; the downstream
 * checks tolerate missing/undefined fields: `config` is optional, and
