+ * v2.7.18: shared MCP client wrapper for the boocontext sidecar.
+ *
+ * Calls into the existing multi-server MCP client infrastructure
+ * (services/mcp-client.ts) which connects to boocontext as a stdio
+ * MCP process defined in data/mcp.json (server name "boocontext",
+ * command: `node /opt/forks/boocontext/dist/standalone.js`).
+ *
+ * The boocontext MCP server is initialized once at app boot in
+ * index.ts via initMcp() and the actual MCP tool call routing is
+ * handled by mcp-client.ts:callTool() — this module is a thin
+ * convenience wrapper that prepends the "boocontext_" server prefix,
+ * normalises the response, and applies inline truncation matching
+ * the same pattern as codecontext_client.ts.
+ *
+ * Usage:
+ *   import { callBoocontext } from './services/boocontext_client.js';
+ *   const resp = await callBoocontext({
+ *     toolName: 'codesight_get_summary',
+ *     args: { directory: '/opt/boocode' },
