Agentic Sandbox v2026.8.8

Released: 2026-08-29 Tag: `v2026.8.8` Previous tag: `v2026.8.7` Compare: `v2026.8.7...v2026.8.8`

What changed

This follow-up patch resolves a Gitea 1.25 scheduling deadlock found by the live v2026.8.7 release. Matrix E2E jobs combined `strategy.max-parallel: 1` with a shared job-level concurrency group. The upgraded scheduler could leave both matrix children in `waiting`, preventing package and release-attachment jobs from advancing. The same shared-group behavior could cancel newly queued conformance jobs.

The redundant job-level groups are removed. E2E backends remain serial within each workflow through `max-parallel: 1`; each qualified host runner has capacity one, so mutable libvirt and `/tmp` state remains host-local and isolated.
