/**
 * Behavioral tests for the phase-command-router adapter (#3788).
 *
 * Shape:
 *   1. Adapter translation — CLI args → hub dispatch shape
 *   2. Result translation — hub result → stdout / error callback
 *   3. Unsupported subcommands — scaffold produces the documented redirect
 *   4. Unknown subcommand — unmapped subcommands produce a well-formed error
 *   5. Integration — real hub + real CJS phase handler invocation
 *
 * Testing rules in force (CONTRIBUTING.md § Testing Standards):
 *   - No readFileSync of source files.
 *   - No mocking of the hub itself — tests use the real CommandRoutingHub
 *     with stub cjsRegistry / sdkLoader entries.
 *   - All assertions on return values and captured call arguments.
