Roots are now tickets with no dependents (nobody depends on them —
top-level goals), and the ASCII tree traverses dependency edges so
prerequisites appear indented beneath the goal that needs them.
JSON edges are now {from: dependent, to: dependency} rather than
{from: blocker, to: blocked}.
All graph-related unit and integration tests updated to match the
new semantics.
