feat: sleep tool and autonomous tick loop #20874
Description
Problem
The agent can't wait for external processes or continue working autonomously between user interactions. Long-running tasks (CI, builds, polling) require constant user prompting.
Proposed approach
Two additions:
- Sleep tool (
src/tool/sleep.ts) — pauses execution for N seconds. Simple, useful immediately for polling loops within a single session. - Autonomous tick loop — a background wakeup mechanism that re-enters the agent loop after a configurable interval when the session is in an autonomous mode.
The sleep tool is self-contained. The tick loop requires client UI support to show status and depends on the detached subtask work (separate issue).
Why it belongs here
Without wait/sleep, the agent can't implement patterns like "run build, wait for it, then check output". The tick loop extends this to fully autonomous sessions.
