GITEA-SETUP.md listed `propose-work` as unbuilt, and this PR builds it without
touching that list, so merging would leave the doc describing a tool as missing
that exists. Strike it the way `gitea-verify` already is: say what was built,
then say what is still missing — here, an end-to-end run, which only the agent
box can do because only it holds a token that can make the POSTs.
