test(web): drop the host-skill context row from the conversation goldens

These goldens were recorded on a machine with personal skills under ~/.dsh and
~/.agents, so every one of them pinned a context-injection row a clean runner
cannot produce — which is why the browser lane failed on CI and passed
locally. master's scaffold fix confines skill-local's host-level roots to the
temp world; re-recording against it removes the row and nothing else.
seeded-history keeps its row: that scenario seeds the event itself.
