## Background
`DOCKER_USERNAME` and `DOCKER_PASSWORD` are commonly used by workflows as ordinary secrets for logging in to a private registry and pushing images. However, the runner also treated these secret names as implicit Docker pull credentials.
These credentials carry no registry information, but they were attached to every pull unconditionally. As a result, a user who configured `DOCKER_USERNAME` / `DOCKER_PASSWORD` secrets for their private registry (e.g. to push images) would have those same credentials sent to Docker Hub when pulling a public image, causing the pull to fail with authentication failure.
## Changes
- Stop using `DOCKER_USERNAME` and `DOCKER_PASSWORD` as implicit pull credentials for job containers.
- Stop injecting `DOCKER_USERNAME` and `DOCKER_PASSWORD` as pull credentials for step containers.
## ⚠️ BREAKING ⚠️
This is a breaking change.
Workflows or runner setups that previously relied on `DOCKER_USERNAME` and `DOCKER_PASSWORD` being implicitly used for Docker image pulls must migrate to an explicit authentication mechanism.
Migration options:
- For private job container images, use `container.credentials`:
```yaml
jobs:
build:
container:
image: registry.example.com/image:tag
credentials:
username: ${{ secrets.REGISTRY_USERNAME }}
password: ${{ secrets.REGISTRY_PASSWORD }}
```
- For private service container images, use service `credentials`.
- For private `uses: docker://...` or private Docker actions, configure Docker authentication in the runner environment before the job starts. For example, run `docker login` on the runner host.
`DOCKER_USERNAME` and `DOCKER_PASSWORD` can still be used as ordinary workflow secrets, for example with `docker/login-action` before pushing images.

Running the full suite under `-race` (dropping `-short`) exposed pre-existing data races in parallel matrix-job execution, fixed by not sharing mutable state across combinations:
- `containerDaemonSocket()`/`validVolumes()` derive per-job values instead of mutating shared `Config`
- `getWorkflowSecrets` builds a fresh map, `rc.steps()` clones each step, and go-git workdir access is serialized
- every write to a shared `Job`'s result/outputs runs under a per-`Job` lock, each combo interpolating outputs from a pristine snapshot (last wins, as on GitHub)
### Test suite
- capability gates (docker / network / host-tools / Linux) replace the `-short` skips, and the suite runs offline via local fixtures (the artifact flow uses an in-process loopback server, only the docker-action force-pull needs the network)
- drops redundant tests, adds a regression test for https://gitea.com/gitea/runner/issues/981 and a docker-in-docker harness (`make test-dind`)

The teardown that removes a job's per-job network and container runs as a `Finally` on the step pipeline in `newJobExecutor`, which only executes after a successful start. When the start itself fails (e.g. a `docker cp` error from a buggy daemon), that `Finally` is skipped, so the network and container leak until Docker's address pool is exhausted and later jobs can no longer create networks.
This tears them down in `startContainer` when the start returns an error, reusing the existing `cleanUpJobContainer` teardown.
Exposed by the daemon regression in https://gitea.com/gitea/runner/issues/981, where every failed `docker cp` leaked a per-job network.

Aligns runner log output more closely with `actions/runner`:
- Strip the whale, rocket, cloud, construction, chequered-flag, and exclamation-mark glyphs from log lines and drop the now-unused `logPrefix` constant.
- Reword `no outputs used step '%s'` → `No outputs registered for step '%s'` (the original was ungrammatical and inaccurate — it fires when `set-output` references an unknown step ID).
- Wrap the docker pull/network/create/start phase of job container startup in a `::group::Starting job container` / `::endgroup::` collapsible section, mirroring `actions/runner`. Since act drives Docker through the SDK rather than the CLI, we can't echo `##[command]/usr/bin/docker create ...` lines verbatim — instead the helper emits a summary inside the group:
```
::group::Starting job container
image: <image>
name: <container-name>
network: <network-name>
::endgroup::
```
- Extracted the emit into a `printStartJobContainerGroup` helper (parallel to `printRunActionHeader` in `step_run.go`) and added a golden-style test `TestPrintStartJobContainerGroupGolden`.
- Drive-by: replace two remaining literal `"raw_output"` strings in `run_context.go` with the existing `rawOutputField` constant.
Closes#935

Removes 88 `nolint` directives (386 → 298) via mechanical, zero-regression cleanups:
- **38 `bodyclose`** in `act/artifactcache/handler_test.go`: replaced by `defer resp.Body.Close()` after each HTTP call.
- **21 dead directives** (`gocyclo`, `dogsled`, `contextcheck`): none of these linters are enabled in `.golangci.yml`, so the directives were doing nothing.
- **29 `testifylint`** directives whose underlying issues were addressed by mechanical rewrites:
- `assert.Nil(t, err)` → `assert.NoError(t, err)`
- `assert.NotNil(t, err)` → `assert.Error(t, err)`
- `assert.Equal(t, true/false, x)` → `assert.True/False(t, x)`
- `assert.Equal(t, 0, len(x))` → `assert.Empty(t, x)`
- `assert.Equal(t, N, len(x))` → `assert.Len(t, x, N)`
- `assert.Len(t, x, 0)` → `assert.Empty(t, x)`
Many `testifylint` directives still apply because they flag `require-error` (i.e. testifylint wants `require.NoError` instead of `assert.NoError` for early bail-out). That's a behavior change (fail-fast vs continue) and out of scope for this purely mechanical cleanup — those can be addressed in a follow-up. Same for `expected-actual`, `equal-values`, `error-is-as`, and the remaining `nilnil` / `unparam` / `forbidigo` / `staticcheck` / `goheader` / `dupl` directives.
`golangci-lint run` is clean. Tests pass for all touched packages.

## Bug fixes
- Fixed "file name too long" errors when running matrix jobs with many or
long-valued matrix parameters. Docker volume and container names are now
bounded to a safe length by hashing the full name with SHA-256, keeping
the result well within the filesystem `NAME_MAX` limit (255 bytes) even
after Docker appends its own suffixes (`-env`, `-network`, etc.).
## Upgrade notes
This change renames the Docker containers, volumes and networks created by
the runner. Resources created by a previous version will **not** be cleaned
up automatically after upgrade and will become orphans.
After upgrading, you can remove the legacy resources with:
```sh
# volumes
docker volume ls -q | grep -E '^GITEA-ACTIONS-TASK-[0-9]+_' | xargs -r docker volume rm
# networks
docker network ls --format '{{.Name}}' | grep -E '^GITEA-ACTIONS-TASK-[0-9]+_.*-network$' | xargs -r docker network rm
```
> **Note:** If multiple act_runner instances share the same Docker daemon,
> make sure no runner using the old version is running before executing the
> cleanup commands above.

Merges the `gitea.com/gitea/act` fork into this repository as the `act/`
directory and consumes it as a local package. The `replace github.com/nektos/act
=> gitea.com/gitea/act` directive is removed; act's dependencies are merged
into the root `go.mod`.
- Imports rewritten: `github.com/nektos/act/pkg/...` → `gitea.com/gitea/act_runner/act/...`
(flattened — `pkg/` boundary dropped to match the layout forgejo-runner adopted).
- Dropped act's CLI (`cmd/`, `main.go`) and all upstream project files; kept
the library tree + `LICENSE`.
- Added `// Copyright <year> The Gitea Authors ...` / `// Copyright <year> nektos`
headers to 104 `.go` files.
- Pre-existing act lint violations annotated inline with
`//nolint:<linter> // pre-existing issue from nektos/act`.
`.golangci.yml` is unchanged vs `main`.
- Makefile test target: `-race -short` (matches forgejo-runner).
- Pre-existing integration test failures fixed: race in parallel executor
(atomic counters); TestSetupEnv / command_test / expression_test /
run_context_test updated to match gitea fork runtime; TestJobExecutor and
TestActionCache gated on `testing.Short()`.
