// Compat shim for the retired `ccd pod …` CLI surface.
//
// RFC 0006 (pod-layer collapse) retires the `ccd pod` surface. This module
// keeps the subcommand names callable so that existing scripts and docs fail
// with a clear pointer instead of an unknown-command error. Every shim fails
// closed: even `pod list` does not delegate silently to `ccd machine list`,
// because the two commands have different report shapes and a silent swap
// would break JSON consumers without a signal.
//
// Forward paths:
//   `ccd pod list`              → `ccd machine list` (different report shape)
//   `ccd pod status`            → `ccd status` / `ccd doctor`
//   `ccd pod init`              → retired (no equivalent; edit repo overlay
//                                 config, or use `ccd session open --pod`)
//   `ccd pod migrate-defaults`  → retired with no automated replacement
//                                 (manual review of profile defaults)
