fix(skill): a DeepSeek Harness worker on its setup guide is refused, not typed into

dsh-TUI 0.19.0 opens a setup guide ("Step 1 of 4") in every session
until a person has finished it once, and the guide's cursor is the same
glyph the skill waits for as the composer: the readiness mark matched on
it in 2 of 2 launches. An Enter there acts on the highlighted step,
which is a sign-in. A spawned worker was handed back "ready" on that
screen, and the first task prompt would have been typed into it.

After the mark, the rendered pane is now read once: a worker that shows
the guide is deleted and the spawn fails with what to do (finish the
guide once from the Run menu). For `local:deepseek` and for a plain
`deepseek` worker alike.

Also says which verb reads a local DeepSeek worker's answer: `sendmark`.
The harness reports the end of a turn, but dsh 0.2.2 renamed its
transcript file and Codeman reads an empty answer from it for now.
