Migrate from stdlib flag to cli.Main() + WithCommands() pattern: - AddChainCommands() registration with persistent --data-dir/--seed/--testnet flags - Explorer subcommand (TUI block explorer, replaces old default mode) - Sync subcommand with headless foreground and --daemon/--stop modes - sync_service.go extracts syncLoop/syncOnce from old main.go - cmd/core-chain/main.go standalone binary entry point - Add go-process dependency for daemon lifecycle Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
