* Archive agents on worktree archive; clean up schedules on archive
Worktree archive used to hard-delete every agent inside it (storage
removed, agent_deleted emitted), losing history along with the worktree.
It now archives those agents instead, so they remain in storage with an
archivedAt timestamp and stay visible in the archived list.
Schedules targeting an archived agent were left as dead records that the
schedule service rejected at run time. AgentManager now fires an
onAgentArchived callback from every archive path (live, stored snapshot,
cascade-to-children), and bootstrap wires it to
ScheduleService.deleteForAgent so those schedules are cleaned up
automatically.
* Push agent_state when archiving stored-only agents; tolerate schedule delete errors
Greptile review on PR #1206 flagged two issues:
1. archiveSnapshot persisted archivedAt to storage but did not emit an
agent_state event for stored-only agents. Connected clients would
keep showing them as active until a full reload. Mirror the dispatch
logic from markRecordArchived: notifyAgentState for live agents,
dispatchArchivedStoredAgent for off-memory non-internal agents.
2. ScheduleService.deleteForAgent used Promise.all, which short-circuits
on the first store error and abandons the rest. Switch to
Promise.allSettled, count fulfilled deletions, and log rejections.
* Tighten agent-manager archive tests after /audit-tests review
- Split "fires onAgentArchived for live, stored, and cascaded archives"
into two single-behavior tests with independent fixtures, so the assertion
array isn't reset mid-test.
- Strict equality on the cascade hook assertion (no more arrayContaining).
- "archiveSnapshot dispatches archived state" now captures the full agent
state event, asserts a dispatch happened, asserts the dispatched agent
id, and asserts the lifecycle is closed.
