* feat: mark threads resolved to hide from sidebar [closes resolve-threads]
Add a resolved flag (thread metadata) so users can clear finished
threads from the sidebar without deleting them. Resolved threads move to
a collapsible "Resolved" group (capped at 20 with a "Show all" link) and
are fully searchable/filterable + paginated on a new /agents/threads
page driven by URL query params. Sending a new message auto-unresolves.

* fix: refresh paginated agent thread lists
Invalidate all agent thread list queries when thread lifecycle events change sidebar data, keeping the new paginated sidebar cache in sync.
