Watching again, or reading once, after the catalog was invalidated or failed
while nothing watched now starts one deduplicated refresh; the observer
refetches on mount. Reconnect repair only refetches watched queries, so an
unwatched catalog stayed stale.
Each subscribe installed its own session and draft store callbacks, so N
watchers received N squared notifications, including for other agents' drafts.
One pair of subscriptions now serves all listeners, and the draft callback
ignores drafts of other agents.
A composer whose agent was removed while it was held was only released on the
next session change. The last holder letting go now checks too, and an archived
agent's idle composer is releasable.
