The rest of the change whose deletions the previous commit carries (its
`git add` stopped at an already-removed path): `fabro_types::RunGraph`
and the `fabro-petri` builder that reads it off the admitted graph, the
server's create, validate, preflight and render paths on Petri's check
alone, the consumers moved to the new shape, the OpenAPI `RunGraph`
schemas with their parity tests, the regenerated TS client, and the
docs naming Petri's diagnostic codes.
