A runner nested behind another runner's docker proxy, as in gitea.com CI, had its `com.gitea.runner.job` label overwritten by the outer proxy, so its job cleanup removed nothing. This failed `TestDockerProxyWithDaemon` depending on the CI host, for example on https://gitea.com/gitea/runner/pulls/1312.
Each proxy now sets `com.gitea.runner.job.<job>` and cleans up by that key, so nested proxies keep each other's. This replaces the `com.gitea.runner.job=<job>` label.

Fixes https://gitea.com/gitea/runner/issues/1213
Fix the DooD regression that mounts `/var/run/docker.sock` as a directory. Keep the Docker proxy available through job and post steps. Clean stale resources before opening it, then remove containers before their networks and volumes during teardown.
Use a unique filesystem probe and preserve socket ownership. Fall back to direct access when proxying is unsupported. Preserve exec output and clean up active streams and failed starts.
Add a real Docker job test for mounted socket access, post steps and resource cleanup.
