`list` already built its query with `q: None, milestones: None` — both
fields were on the request it was sending. So full-text search over
title and body is a flag, not a new verb, and a text match is only
useful composed with the other filters anyway.
The trailer was the real defect. It fired on `count == limit`, but the
forge clamps page size to its own `api.MAX_RESPONSE_ITEMS`: ask for 400,
get a full 50, and `50 != 400` kept it silent — suppressing the warning
in precisely the case where the truncation is invisible. It now reports
the real total from `X-Total-Count`, which the response header struct
already parsed and the call site discarded. The requested limit is not
clamped client-side: that ceiling is the remote's configuration, not
ours.
