/**
 * `agentsmarket init` — generate BIP-39 mnemonic, derive secp256k1 keypair, register.
 *
 * 1. Creates:
 *      ~/.config/agentsmarket/mnemonic.txt   — 12-word phrase (PRIMARY backup)
 *      ~/.config/agentsmarket/agent.key      — secp256k1 private key (hex)
 *      ~/.config/agentsmarket/config.json    — public config (agent_id, network)
 * 2. Registers on server (POST /v1/agents/register). If unreachable, init still
 *    succeeds locally — retry later with `agentsmarket register`.
 *
 * IMPORTANT: This is a one-time setup.
 * - mnemonic.txt = wallet backup. Import into Trust Wallet to monitor/send funds.
 * - agent.key = signing key for CLI. Derived from mnemonic.
 * - If you lose BOTH, you lose the agent identity and any associated balance.
