`reportStepError` reported every step error as FAILURE, including a `context.Canceled` from a docker file-command read cancelled at job finalization — non-deterministic red CI. Classify `context.Canceled` as an interruption instead (deferring to the job context), so a genuine cancel reports cancelled and a stray teardown cancellation is ignored, never a failure.

`containerReference.id` was cached from `Create()` and never re-validated, so a container torn down out-of-band (AutoRemove on an unexpected exit, daemon-side cleanup, sibling-job race in a parallel matrix) left a stale id behind. The next `Copy`/`Exec` then hit the daemon with that dead id and failed the otherwise-successful job with `Could not find the file /var/run/act/ in container <id>`.
`find()` now `ContainerInspect`s the cached id and clears it only on a definitive `NotFound`; transient errors trust the cache so cleanup pipelines don't abort on a daemon blip. Operations that need a live container (`copyContent`/`copyDir`/`CopyTarStream`/`exec`/`GetContainerArchive`) fail fast with a clear `container "<name>" does not exist` instead of the daemon's generic empty-id error.

Fixes#956.
Pseudo-TTY allocation is now an explicit, runner-wide opt-in via `runner.allocate_pty`, applied to both host and docker backends. Default is off, matching GitHub `actions/runner`.
```yaml
runner:
allocate_pty: false # default
```
**Before:** the host backend hardcoded `if true /* allocate Terminal */` and the docker backend used `term.IsTerminal(os.Stdout.Fd())`. As a result, `docker build` (and other TTY-aware tools) saw a TTY and emitted cursor-control redraw frames that flooded captured logs with thousands of duplicate-looking progress lines — only on host-mode runners in production, and on docker-mode runners when the daemon happened to be launched from a shell rather than a service.
**After:** both backends consult `Config.AllocatePTY`. The `term.IsTerminal` heuristic is gone, so behavior no longer depends on whether the daemon has a controlling terminal.
**Reproduction:** running `docker build` through `HostEnvironment.Exec` with output captured to a buffer:
| | Before (`if true`) | After (`AllocatePTY=false`) |
|---|---:|---:|
| bytes captured | 18,167 | 1,048 |
| ANSI CSI sequences | 556 | 0 |
| cursor-up `\e[1A` | 181 | 0 |
**Side fix:** `ptyWriter.AutoStop` is now `atomic.Bool`. The field is written from the exec goroutine after `cmd.Wait()` and read from the `copyPtyOutput` goroutine via `ptyWriter.Write`; existing tests never tripped the race detector because their commands produced no output before exit. The new host-mode test does.

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.

Closes#848. Addresses [GHSA-82g9-637c-2fx2](https://github.com/go-gitea/gitea/security/advisories/GHSA-82g9-637c-2fx2) and the follow-up points raised by @ChristopherHX and @haroutp in that thread.
The change is breaking only for `cache.external_server` which uses auth via a pre-shared secret.
## How auth works now
1. **Runner starts** → opens the embedded cache server on `:port`. Loads / creates a 32-byte HMAC signing key in `<cache-dir>/.secret`.
2. **Runner receives a task** → calls `handler.RegisterJob(ACTIONS_RUNTIME_TOKEN, repository)` before the job runs, defers a revoker that removes the credential on completion. Registrations are reference-counted so a stray re-register cannot revoke a live job.
3. **Job container runs `actions/cache`** → the toolkit sends `Authorization: Bearer $ACTIONS_RUNTIME_TOKEN` on every management call (`reserve`, `upload`, `commit`, `find`, `clean`). The cache server's middleware looks the token up in the registered-jobs map: miss → 401; hit → the job's repository is injected into the request context.
4. **Repository scoping** — every cache entry is stamped with `Repo` on reserve; `find`, `upload`, `commit` all verify the caller's repo matches. A job in repo A cannot see or poison a cache entry owned by repo B, even when both reach the server over the same docker bridge. GC dedup also groups by `(Repo, Key, Version)` so one repo can't age out another.
5. **Archive downloads** — `@actions/cache` does not attach Authorization when downloading `archiveLocation`, so the `find` response is a short-lived HMAC-signed URL: `…/artifacts/:id?exp=<unix>&sig=<hmac>`, 10-minute TTL, signature binds `cacheID:exp`. Tampered, expired, or foreign-secret URLs get 401.
6. **Defence-in-depth** — `ACTIONS_RUNTIME_TOKEN` is added to `task.Secrets` so the runner's log masker scrubs it from step output.
## `cache.external_server` (standalone `act_runner cache-server`)
Operators set `cache.external_secret` to the same value on the runner config and the `act_runner cache-server` config. The `cache-server` then runs with bearer auth on the cache API and exposes a control-plane at `POST /_internal/{register,revoke}` (gated by the shared secret). The runner pre-registers each task's `ACTIONS_RUNTIME_TOKEN` with the remote server before the job runs and revokes it on completion. Same per-job auth + repo scoping as the embedded handler, just over the network.
`cache-server` refuses to start without `cache.external_secret`; runner config load also fails when `cache.external_server` is set without `cache.external_secret`.
## User-facing changes
- **One-time cache miss after upgrade.** Pre-existing entries in `bolt.db` have no `Repo` stamp and won't match any job — they'll be evicted by the normal GC. First job per cache key rebuilds its cache.
- **`cache.external_server` deployments must add `cache.external_secret`.** Breaking change for anyone running a standalone `act_runner cache-server`: set the same `cache.external_secret` in both the runner config and the cache-server config. Without it neither side starts.
- **No config changes required for the default setup.** Runners using the embedded cache server (the common case) keep working without any yaml edits; the auth mechanism is invisible to workflows.
