silverwind dcba546cb3 fix: align process handling and fix Windows crashes (#1376)
The intermittent Windows test crashes came from step errors formatting a nil `rc.Run`. `fmt` recovers the nil dereference, but on CPUs with AMX the recovered fault overflows into the heap (https://github.com/golang/go/issues/81238). The errors now name the job, and the Windows test VM hides AMX and runs on UTC, so cached boots no longer jump back 8 hours mid-test.

Windows commands now start suspended and resume once they are in their job objects, so no child escapes them. That drops the process scan reading other processes' memory and the last `unsafe` code, which `depguard` now denies. Step processes outlive a crashed runner, and commands are no longer looked up in the runner's working directory, both as with GitHub's runner.

Like GitHub's runner, host jobs on Linux and macOS now end the processes carrying the job's `RUNNER_TRACKING_ID`, and image pulls and Dockerfile action builds are retried.

silverwind d6f5b68a0d enhance: test on Windows and fix what it found (#1348)
Adds a weekly and on-demand workflow that runs the cross-compiled tests on Windows Server 2025 Core in a [dockur/windows](https://github.com/dockur/windows) QEMU VM, and fixes the Windows bugs it found in host and UNC paths, env handling, shell quoting, post-task scripts, health checks, checkout, action symlinks, step summaries, Git client certificates and docker mode from a Windows host.

Host-mode steps now emit UTF-8, `bash` falls back to Git's bash instead of the WSL launcher, the runner can run as a native Windows service, steps can keep background helpers with `RUNNER_TRACKING_ID`, and Windows arm64 binaries are released.

silverwind 5fd2f82735 test: fix race in TestTreeKillCancelBeforeCaptureKillsTree (#1360)
`TestTreeKillCancelBeforeCaptureKillsTree` fails intermittently on CI, e.g. https://gitea.com/gitea/runner/actions/runs/1155856.

Dash, the Ubuntu `/bin/sh`, points a background job's stdin at `/dev/null` before applying its redirections, so `cat <&0 &` read EOF and exited at once and the liveness check raced it. The pipe is now handed over on fd 3, which dash leaves alone.

silverwind fe2a66dc25 fix: align runner behaviours (#1338)
Contains a number of small bug fixes where jobs behaved differently from GitHub or failed silently.

1. Hooks fail on a refused `::set-env::` or `::add-path::` and no longer inherit the last step's identity
1. Docker build, exec and wait errors are returned instead of swallowed, token-only registry credentials work, logs of `--tty` services decode
1. Env files split lines like GitHub on each OS, so a carriage return is kept on Linux and CRLF ends a line on Windows, empty heredoc names or delimiters are rejected
1. Post steps run after their pre step even when main was skipped, composites see undeclared inputs, `runs.args` wins without `with.args` being parsed
1. Docker actions skip evaluating defaults of inputs given in `with` and read `entryPoint` and `args` in any case, a lowercase `dockerfile` is found, undeclared inputs get GitHub's warning
1. A user-set `CI` is kept, `GITHUB_REPOSITORY_ID` and the other missing `GITHUB_*` variables are exported
1. `timeout-minutes` can read the step's own `env`, a step-level `ACTIONS_ALLOW_UNSECURE_COMMANDS: false` beats a job-level `true` while the runner's own opt-in still wins, `pwsh` quotes the script path
1. A step `env:` given as one expression such as `${{ fromJSON(matrix.env) }}` is applied, `hashFiles` fails with GitHub's messages on script errors and after 120 seconds, a job image without node still gets an empty hash
1. A step whose command files cannot be reset fails instead of importing stale ones, a timeout between steps fails the job instead of reporting success
1. One named volume can be mounted at several paths, host-mode PTY steps keep their last output when they fail, host scratch directories are removed when job setup fails
1. Cancelling a step right after it starts kills its whole process tree
1. Cache prefix restores pick the newest entry created within the same second, also on S3, cache commits with a wrong size are rejected
1. Artifact chunks are written at their offset, download URLs are escaped, listing a run without artifacts no longer crashes
1. Poll backoff reaches `fetch_interval_max`, proxy passwords are masked in more forms, secrets are also masked in step names and in their quoted form in the runner log, a failed final report is logged
1. On Windows hosts a differently cased unsecure-commands opt-in or proxy variable counts, and an early cancel no longer leaks a job object handle
1. Interactive `register` prompts for a missing token and stops on SIGTERM, `exec --list --detect-event` no longer panics without events, `config set` works on `cache.s3` keys

silverwind d882311ec6 refactor: remove dead code and consolidate tests (#1335)
Removes dead code and redundant logic and consolidates tests, so there is less to read and maintain. No behavior change.

1. **act/runner**: inline single-use wrappers, compile regexes once instead of per call, embed the trampoline as a string, drop the unused legacy result of `parseActionCommand`
2. **act/container**: `sanitizeConfig` and `mergeContainerConfigs` stop returning the configs they already mutate in place, drop never-set option fields and the unused `user` parameter of `ExecWithCmdLine`
3. **act/common and cache server**: drop the unused `Trace`/`Tracef` loggers and the short SHA of `FindGitRevision`, `RegisterJob` releases through `RevokeJob`
4. **daemon, poller and reporter**: one shutdown wait for both poll modes, drop an unreachable fetch timeout branch, guard the reporter's last report time with its existing lock instead of an atomic
5. **build**: drop unused Makefile and release workflow variables, collapse the goreleaser ignore list to the same build targets
6. **tests**: fold near-duplicate tests into tables with shared setup

Throughout, hand-rolled logic gives way to `cmp.Or`, `strings.Cut`, `slices` and `min`/`max`.

silverwindandbircni ed940db4f0 fix: don't fail host steps over a leftover holding their output (#1323)
A successful host step whose background child kept its output open failed with `exec: WaitDelay expired before I/O complete`. Like GitHub's runner (`ProcessExitedHandler` in https://github.com/actions/runner/blob/main/src/Runner.Sdk/ProcessInvoker.cs), the step now succeeds after the drain timeout.

The leftover is killed only on Windows, as GitHub does there. A step whose timeout or cancellation hits during the drain still fails.

Lunny Xiaoandbircni c3c647ef83 test: use t.Context() instead of context.Background() (#1306)
The test context is cancelled when the test ends, so anything still holding it stops instead of leaking into the next test. Uses inside `t.Cleanup`, `defer` and `go func` blocks are left alone, as the context is already cancelled there.

Stacked on https://gitea.com/gitea/runner/pulls/1305.

bircniandsilverwind 7bec310002 fix: stop host-mode jobs from leaking processes on Windows (#1080)
## Problem

On host-mode Windows runners, a job can leave processes running after it finishes,
and those leftovers hold file handles that block deletion of the workspace.

Today a step's tree is only torn down when the step is *cancelled*
(`process.Killer`). A step that completes leaves whatever it spawned alive, and
the existing workspace scan in `terminateRunningProcesses` misses two shapes of
leftover: orphans whose parent already exited (no tree to walk, and their
executable often lives outside the workspace), and processes that merely *run in*
the workspace but reference no path from it — `Win32_Process` exposes no working
directory, so the scan cannot match them.

## Solution

Two additions in `internal/pkg/process`, both no-ops outside Windows:

- **`process.Group`** — a job-scoped Windows Job Object created with
  `JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE`. Step processes are assigned to it before
  they get their own `Killer`, so the step's job nests inside the job's:
  cancellation still kills exactly the step's tree, while `Remove` closing the
  group makes the kernel terminate everything still assigned, whatever its
  parentage. The kernel also drops the handle when the runner exits, so a crashed
  runner cannot strand processes.

- **`process.KillProcessesWithCWDUnder`** — a best-effort net for processes that
  never joined the job (started via a service or scheduled task). It reads each
  process's working directory from its PEB and terminates those under a workspace
  dir. Processes it cannot open are skipped.

- fix Windows-only golangci-lint findings in `lp_windows.go` and process killer handle cleanup
- add a `lint-go-windows` target that runs golangci-lint with `GOOS=windows`
- include the Windows lint pass in `make lint` so Ubuntu CI covers `_windows.go` files

Nicolas 007717956a feat: Add optional runner.post_task_script hook after task cleanup (#1026)
- Adds `runner.post_task_script` and `runner.post_task_script_timeout` (default `5m`) to run a host executable after each task’s built-in cleanup (post-steps, container teardown, bind-workdir removal).
- Stops task heartbeats via `Reporter.StopHeartbeats()` while the script runs so Gitea won’t assign overlapping work; the final task acknowledgement still happens in `reporter.Close()`.
- Script output goes to the runner process log; non-zero exits are warned only and do not change the job result.
- Documents lifecycle, offline behavior, timeouts, and Windows limits (`.ps1` not supported yet) in `docs/post-task-script.md`.
