docs(changelog): include Kiro CLI runtime, drop assignee-default line

Per release sign-off: Kiro CLI ACP runtime ships in v0.2.19 once the
chat-mode regression is fixed, so it goes back into the headline. The
"create-issue remembers last assignee" line is dropped from features
to keep the list to four spotlight items.
