/**
 * @deprecated The supported programmatic surface is `gsd-sdk query` (SDK query registry)
 * and the `@gsd-build/sdk` package. This Node CLI remains the compatibility implementation
 * for shell scripts and older workflows; prefer calling the SDK from agents and automation.
 *
 * GSD Tools — CLI utility for GSD workflow operations
 *
 * Replaces repetitive inline bash patterns across ~50 GSD command/workflow/agent files.
 * Centralizes: config parsing, model resolution, phase lookup, git commits, summary verification.

// bridge). CJS handlers are retained as fallback when SDK is unavailable.
//
// NOTE: migrate-config, detect-custom-files, config-path, and find-phase
// are CJS-native special cases; see comments inline.

// Shared loader for the synchronous SDK runtime bridge; see
