HUX-03: GET /hux/v1/search now accepts include=message_text, an
explicit opt-in that scans the stored message events of the 100 most
recently active candidate conversations. Forgotten (tombstoned)
conversations, private-mode conversations, restricted events and fully
redacted events never match; the default indexed-fields search and its
response contract are unchanged (the shipped UI keeps requiring
message_text in not_indexed). Paginated mode uses one deterministic
total order (score desc, updated_at desc, id) with an offset cursor.
