AEP 0.54.0

• govern workflow render --format mermaid writes a diagram a Markdown document renders
  itself. The other three formats are assets: a reader needs a viewer, and a repository that wants
  the figure beside its prose commits a binary and has to remember to regenerate it. So a README
  explaining a workflow got a diagram somebody typed, which is true on the day it is typed — the
  org-brain instance had one whose arrows were the order the states were written in rather than the
  transitions, and which carried no guard at all. The Mermaid output carries the guard on each
  arrow, which states are terminal, and the requires of each state as a note, and it is text, so
  the command that wrote it can be run again in a gate.

• govern workflow instruct --map <step-map> also says what runs in each state. A workflow
  declares what may happen and never what does; the step map is the other half, separate because one
  workflow governs instances whose programs differ. Read alone the instructions were honest and not
  actionable — a reader of a state learned the rule it must satisfy and not that a program called
  brain ledger acquire is what satisfies it. With a map each state names its steps in the author's
  order, marked command, llm or operator. A map covering a state with no steps says the driver
  runs nothing there; a map silent about a state says nothing, because those are different facts.
  --map needs --id: one map is written against one workflow, and applying it across a directory
  would render some documents saying what runs and some not, with nothing saying which.

  The step map crosses into aep-render as steps::StepsView, a plain struct the caller builds —
  the seam run::RunView already uses, which is what keeps aep-domain that crate's only
  dependency.

• A refused drive resume names a route that exists. It advised --restart, which no drive verb
  parses, so a reader who followed it got a second refusal — a bare usage error that reads as their
  own mistake rather than the message's. It now names drive run, and a test walks the whole
  command tree to hold every flag the refusal names to a flag some verb accepts.
