* 💄 style(topic): show error alert icon with tooltip on failed topics

* ✨ feat(topic): merge attention-needing topics into one "Needs attention" group

Collapse the unread-completion, failed, and waitingForHuman states into a single
top "pending" status bucket (待处理 / Needs attention) so the sidebar surfaces
everything that needs the user's attention in one place.

- groupTopicsByStatus now buckets those three states into `pending`, taking a new
  `unreadTopicIds` set (unread completions are a client-only state).
- Server STATUS_SORT_RANK floats `failed` to the top alongside `waitingForHuman`
  so failed topics stay on the first page and don't drop out of the group.

* 💄 style(topic): pin the "Needs attention" group above favorites

The pending bucket already sorts above running, but the synthetic favorite group
was prepended ahead of it. Hoist pending to index 0 so attention-needing topics
sit at the very top of the sidebar, above both favorites and running.

* 🐛 fix(heterogeneous-agents): pin resolved cwd onto remote-CC new topics

Remote CC dispatched the run with the correct working directory (the
precedence chain falls back to the agent's per-device pick), but a
brand-new topic was created without `metadata.workingDirectory`, so the
sidebar grouped it under "No directory" / 无目录.

Unify the three drifting server-side cwd-precedence sites behind one
pure helper (`resolveDeviceWorkingDirectory`) and persist the resolved
cwd back onto a freshly-created topic so grouping, next-turn reuse, and
workspace-init scan all agree.
