* fix(native-chat): a chat you return to drops background tasks that finished while it was hidden A background command that finished while its chat pane was hidden stayed in the strip as running, its timer counting for hours, and Stop failed with "The background task wasn't stopped." The pane stops listening while hidden, so it missed the "no tasks" update; once the idle sweep stopped the agent, the host reopened the pane's subscription without any roster at all, and the client reads a missing roster as "unchanged". The roster now rides each subscriber's frames the way the slash-command list and the message queue already do. The subscriber registry reads it from the host's child records on a subscriber's first frame and on every snapshot and reset, and re-sends it to each subscriber whose last copy differs when the records change. The channel always answers: a conversation with no running child is "none" whether or not an agent holds it. Ordinary journal batches never read it. This also fixes the reverse case: a snapshot or reset sent to a live pane carried no roster, which cleared a still-running task from the strip until the roster next changed. The client treats a resumed subscription's first batch as stating the roster, so a pane reconnecting to an older host that still omits it drops its stale copy too. Fixes #24227 * refactor(native-chat): require the background-task roster read and drop the unused close observers The host's delivery layer now requires every hook it is built with, so production wiring cannot leave out the roster read (an opening frame without it reads as "no tasks" to current clients). The conversations map's close observers lost their only caller in this PR and are removed. The reducer test comment states the old-host omission rule precisely. * refactor(native-chat): keep structured-agent-session-host.ts within the line limit Main brought the host file to the 300-line lint limit, and this PR's roster wiring adds one line. Name the lease reconciler's type by its factory, as the neighbouring fields do. * test(native-chat): build the roster test's Claude provider handle with claudeProviderHandle Main made the provider handle opaque (#24991); build it with the existing helper, as main's own tests now do.
