On an issue page, Cmd+K now offers Fold All Comments / Unfold All
Comments. Folding collapses every thread card via the persisted
comment-collapse store; unfolding also expands resolved threads, whose
session-only expand state moves from issue-detail useState into a new
core resolved-expand store so the palette can drive it (MUL-4763).

collectThreadReplies walked the parent_id tree depth-first, so an agent
reply forced to nest under its trigger comment rendered before earlier
sibling replies (A-D-B-C instead of A-B-C-D) whenever the agent returned
late. Sort the collected subtree by created_at (id tie-break) so the
thread reads in arrival order — the same order the server already feeds
agents via `comment list --thread` (ListThreadCommentsForIssue).
All other consumers of the array (resolution derivation, fold bars,
counts, deep-link) are order-independent.
