/**
 * Direct CLI Tool Commands
 *
 * Exposes GitNexus tools (query, context, impact, cypher) as direct CLI commands.
 * Bypasses MCP entirely — invokes LocalBackend directly for minimal overhead.
 *
 * Usage:
 *   gitnexus query "authentication flow"
 *   gitnexus context --name "validateUser"
 *   gitnexus impact --target "AuthService" --direction upstream
 *   gitnexus cypher "MATCH (n:Function) RETURN n.name LIMIT 10"
 *
 * Note: Output goes to stdout via fs.writeSync(fd 1), bypassing LadybugDB's
 * native module which captures the Node.js process.stdout stream during init.
 * See the output() function for details (#324).
