Ran the full desktop-client flow against production (real account) and updated
the doc to the verified responses:
- capabilities model = gpt-5.4; modes still returned but ignored.
- agent object: access_token is "" (AM issues none — connect via A2A api_key),
subdomain is a host (dep-xxx.taijiagnet.com), status starts Pending; real
binding_ids; shown as "生产实测" examples.
- §4: clarified the template `model` field is a role-tier hint (opus), not the
runtime model (gpt-5.4 injected at deploy).
- §5: stop currently fails / delete returns runtime_cleanup:"failed" (AM stop
missing + delete bug); HM removes the local record regardless.
- §6: must wait for status=running / health 200 before connecting; noted the
agent currently stays Pending and the subdomain isn't reachable yet (AM side).
- top banner: per-endpoint production verification note.
