* feat(issues): mention parent assignee in child-done system comment (MUL-2538)
Per Bohan's product call on MUL-2538 ("方案 C"), the platform's child-done
system comment now @mentions the parent assignee — member, squad, or
agent — and the platform fires the matching side effect explicitly:
- agent → mention task via TaskService.EnqueueTaskForMention
- squad → leader task via TaskService.EnqueueTaskForSquadLeader
- member → 'mentioned' inbox row + EventInboxNew broadcast
The generic comment listener still short-circuits on author_type='system'
(see notification_listeners.go) so smuggled mention links in the child
title can never light up unrelated members; the parent assignee mention
is the only side effect, and it is fired from the handler with explicit
guards rather than the listener path.
Guards retained / added:
- Comment-fire gates from prior PR unchanged (status transition, parent
state, no parent).
- Loop guard: skip trigger when child and parent share the same assignee
(same agent / same squad / same member). The comment + mention still
render so the timeline tells the full story; the second task does not
fire.
- Idempotency: HasPendingTaskForIssueAndAgent dedupes rapid-fire enqueues
for the same parent (back-to-back child completions).
- Readiness: archived agents / missing runtimes are silently skipped.
Tests:
- TestChildDoneMentionsParentAssignee_{Agent,Member,Squad} verify the
mention link + the matching trigger / inbox row.
- TestChildDoneSelfTriggerGuard_SameAgent asserts that an agent assigned
to both the child and the parent gets the comment + mention but no
second task — the documented loop break.
- TestChildDoneNotifiesParent updated: when the parent has no assignee
(its existing fixture), no routing mention should appear; the assigned
branches are exercised by the new cases above.

* feat(issues): skip child-done parent notification for human assignees (MUL-2538)
Humans read their own timeline manually — an automated system comment
is pure noise for member-assigned parents, and there is no agent task
to trigger. Skipping the notification entirely also removes the mention
question (no comment → no mention → no inbox row).
The agent / squad / unassigned branches stay unchanged.

* fix(issues): close cross-squad shared-leader loop in child-done dispatch (MUL-2538)
Elon's review of PR #3065 flagged that triggerChildDoneAgent and
triggerChildDoneSquad only compared the child's direct assignee, so a
child-done event could still wake the same agent when:
- parent assigned to agent A, child assigned to a squad whose leader is A;
- parent and child assigned to two different squads sharing the same
leader agent.
Replace the per-side checks with a single effectiveChildAgentOwner helper
that reduces the child to "the agent that would actually act on it" (the
agent assignee, or the squad's leader) and lets both trigger paths compare
apples to apples. Add coverage for both newly-blocked cases, and tighten
the documented side-effect semantics (squad triggers leader only — no
member fan-out; notification_preference is not consulted, downstream
agent_task / inbox pipeline still respects mutes).
Also fix the member-skip test fixture to write user_id, matching the
production invariant that issue.assignee_id for assignee_type='member'
references user_id (validateAssigneePair, server/internal/handler/issue.go).
