"""Task #162: claim_doc_task checks out the task branch + verb hints.

Smoke-11: be-doc claimed an awaiting_documentation task but its clone
stayed on the default branch (the branch was created in the dev's
separate clone). roboco_docs_write / commit failed BRANCH_MISMATCH and
the doc looped (i_am_blocked Not Found, give_me_work pointed at a dev
verb). Primary fix: claim_doc_task checks out the task branch into the
documenter's workspace. Facet (d): give_me_work's next-hint is now
role + status aware.
