Creating an "overarching" configurable ceremony type

Captured from a conversation that @aarongable and I had:

Create a new ceremony config which acts as a meta-config, saying "process these config files in this order, sending the outputs of this step to the inputs of that step"

A declarative replacement for what currently lives in run.sh and some hard-coded paths in the config files.

As an added feature, the program should be able to output a dot file diagramming the hierarchy

digraph structs {
    node [style=filled shape=note fontname=Arial];
    rankdir=TB;
    splines=ortho;
    pad="0";
    ranksep=".8";
    nodesep=".3";
    concentrate=true;
    {rank = same; dstrootcax3; isrgrootx1; isrgrootx2}
    {rank = same; leax1; leax3; r3; e1;}
    
    subgraph R {
        dstrootcax3 -> isrgrootx1 -> isrgrootx2 [arrowhead=vee]
        dstrootcax3 [label="DST Root CA X3" fillcolor=orange];
        isrgrootx1 [label="ISRG Root X1" fillcolor=orange];
        isrgrootx2 [label="ISRG Root X2" fillcolor=cadetblue3];
    }
    subgraph IR {
        isrgrootx1 -> leax1 -> ee1 [arrowhead=vee]
        isrgrootx1 -> leax3 -> ee2 [arrowhead=vee]
        isrgrootx1 -> r3 -> ee3 [arrowhead=vee]
        dstrootcax3 -> leax1 [color=gray40 style=dotted arrowhead=vee]
        dstrootcax3 -> leax3 [color=gray40 style=dotted arrowhead=vee]
        dstrootcax3 -> r3 [color=gray40 style=dotted arrowhead=vee]
        leax1 [label="LEA X1" fillcolor=orange];
        leax3 [label="LEA X3" fillcolor=orange];
        r3 [label="R3" fillcolor=orange];
        ee1 [label="EE"];
        ee2 [label="EE"];
        ee3 [label="EE"];
    }
    subgraph IE {
        isrgrootx2 -> e1 -> ee4 [arrowhead=vee]
        e1 [label="E1" fillcolor=cadetblue3];
        ee4 [label="EE"];
    }

Start by examining run.sh and the existing ceremony config files to understand the current ordering, hard-coded paths, and data flow. Define how the overarching config represents those steps and how the program should emit a Graphviz dot diagram; done should include a working declarative replacement and the requested hierarchy output.
