Agentic Sandbox v2026.8.7

Released: 2026-08-29 Tag: `v2026.8.7` Previous tag: `v2026.8.6` Compare: `v2026.8.6...v2026.8.7`

What changed

This follow-up patch fixes process cleanup in the shared CI heartbeat helper. Gitea Runner 3 waits for inherited output descriptors to close when a step finishes. The previous helper stopped its loop shell but could leave that shell's active `sleep` child alive briefly, causing the runner to report `WaitDelay expired before I/O complete` even after a successful command.

The helper now terminates and reaps the active child before the loop shell. This affects CI process hygiene only; application runtime behavior and persisted state are unchanged.
