"""Regression: draft/seal coordination dicts are bounded (PR 85796
review, M1).

_sealed_draft_by_chat's key embeds a per-turn identity, so every
completed turn added a permanent entry — unbounded growth for the life
of a long-running gateway process. _open_draft_by_chat could grow the
same way via abandoned entries. Both now FIFO-evict at the same cap the
sibling bounded caches use (and the connector's own tombstone store).
