Without a docker daemon six `act/runner` tests failed instead of passing. A dry run still created and removed job networks, the job teardown dropped the dry-run flag along with every other context value, and the container mocks asked the daemon for the runner arch.
This also speeds up the tests and CI without dropping assertions. Most of the time went to git and docker round trips, which are now pinned, batched or coalesced, and the dind and e2e steps cache or overlap more of their setup. On CI, `act/runner` went from 77s to 55s and `test-dind` from 108s to 55s. Locally, `act/runner` without docker went from 53s to 7s.
Split out of https://gitea.com/gitea/runner/pulls/1348, which adds Windows CI on top. The go cache changes moved to https://gitea.com/gitea/runner/pulls/1350.

- Look up containers by name instead of listing all of them
- On Linux, cache the docker proxy discovery instead of starting a probe container per job
- Download a job's actions concurrently and share identical fetches between concurrent jobs
- Cache `runner.arch` per run and poll service health every 250ms
- Cache server: queue on an in-process lock instead of polling the database file lock, upload S3 objects up to 64MiB in one request and larger ones in 4 concurrent parts

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.

Podman creates a missing bind source instead of rejecting it, so the Docker proxy probe passed even when the daemon could not see the runner's files. Jobs of Podman runners in a container got an empty directory at `/var/run/docker.sock` (https://gitea.com/gitea/runner/issues/1193#issuecomment-1700501).
The probe now binds the directory and stats its marker through the created container. A runner in a container stats the marker through its own container, so it no longer creates probe containers, which cost up to 2s per job. `make test-dind TARGET=podman` runs the probe against Podman in CI.

Containers a job starts through its Docker socket, for example `docker run -v "$PWD:/src"`, `./data:/data` in docker compose, or actions like dockerfile-roast, can now bind-mount the workspace and other paths the job sees, as on a host, without `bind_workdir`.
The per-job Docker proxy rewrites container and volume create requests. A bind source, or the device of a `local` volume with `o: bind`, that lies under one of the job container's mounts is pointed at that mount's path on the daemon, read from inspecting the job container. Paths that already name a daemon path, like `GITEA_DOCKER_WORKSPACE`, and paths outside the job's mounts pass through unchanged.
The proxy now also starts when the runner runs in a container given the host's Docker socket, by placing its socket in the runner's working directory, and in rootless dind, by granting the daemon socket's group through an ACL.

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.

1. Add `GITEA_DOCKER_WORKSPACE` which holds the workspace path as the daemon sees it, enabling `${GITEA_DOCKER_WORKSPACE:-.}/data:/app/data` in a compose file without having to resort to `bind_workdir` (which causes much more problems like breaking `actions/cache` because of unstable workspace paths).
2. Add container/network/volume cleanup for containers started within jobs, for example via `docker compose` inside a job. It works by running a lightweight docker socket proxy and injecting a `com.gitea.runner.job` label into every container creation and that label is used to remove containers started by that job at the end. Perf impact of this is near-zero.
