feat(kimi-code): show live background agent activity in the /tasks panel (#2816)
* feat(kimi-code): show live background agent activity in the /tasks panel

Background agents (run_in_background or Ctrl+B) showed no run details:
the /tasks panel only had static metadata, and its output view stays
"[no output captured]" until completion because agent tasks capture
output only once at the end.

Tee child-agent events into a bounded in-memory per-agent activity
store segmented by the engine's own turn.step.started events (recent
10 steps, bounded text/output tails). The /tasks preview pane now
shows a live activity preview for agent tasks, and Enter/O opens a
full-screen detail view rendering step-grouped Markdown text and
per-tool results through the main transcript's renderers, with Ctrl+O
to expand. Agent tasks without an in-memory record (e.g. lost after
resume) fall back to the captured-output view.

* feat(kimi-code): retain 20 recent steps in the background agent activity view

* fix(kimi-code): cap the streaming-args buffer in the subagent activity store

* chore(kimi-code): simplify the background agent activity changeset

* fix(kimi-code): drop activity records of foreground-only subagents at terminal state

* fix(kimi-code): cap retained tool argument strings in the subagent activity store

* test(acp-server): retry temp-dir cleanup to deflake ENOTEMPTY on CI

* fix(kimi-code): tighten subagent activity store lifecycle edges

- drop delta-only arg buffers when their step is evicted
- keep records of spawn-time background agents even when the task sync lags
- mark records terminal on background.task.terminated for stopped agents
  that never emit subagent.failed

* fix(kimi-code): release leftover arg buffers when an activity record turns terminal

* fix(kimi-code): prune foreground-only activity records when the main turn ends
