/**
 * Unified `perp portfolio` command — replaces:
 *   - `perp account balance` (single-exchange detail)  → `perp portfolio -e <ex>`
 *   - prior `perp portfolio`                            → `perp portfolio` (rebuilt)
 *   - `perp status`                                     → `perp portfolio --arb`
 *   - `perp status --health`                            → `perp portfolio --health`
 *   - `perp dashboard`                                  → `perp portfolio --serve`
 *
 * Modes (mutually exclusive, picked by flag):
 *   snapshot (default) | health | watch | serve
 *
 * I/O contract:
 *   - Text mode  → human-friendly tables + side-by-side panels (status-like)
 *   - JSON mode  → canonical envelope (see spec); arb / health / serve keys conditional
 *   - --stdin    → read JSON args from stdin, overrides CLI flags
