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

A new node can run pods before its kubelet has a serving certificate, so the first exec into the job container fails with `error dialing backend: remote error: tls: internal error` and the job fails during setup.
That exec only reads the arch and PATH, so it now retries for up to a minute unless the API server rejects it (4xx) or the command ran.

On Kubernetes a service is reached by its id made a DNS label, so some service ids might become unreachable. For example, the `devstoreaccount1.azurite.local` service of Gitea's [MSSQL tests](https://github.com/go-gitea/gitea/blob/2fe74d3cdd5184a7e22e32e47772caa78d077489/.github/workflows/pull-db-tests.yml#L229) is only in the pod's hosts as `devstoreaccount1-azurite-local`, while the tests connect to the id as written. Container names must be DNS labels, but `hostAliases` accepts DNS subdomains, so an id that is one is now added there too, and to `no_proxy`, as on Docker where a service is reached by its id.
The warning for a service not reachable by its id now also covers ids that differ only in case, as Kubernetes hostnames are lowercase.

The Kubernetes backend extracted CopyDir archives at "/" with entries like
"var/run/act/actions/<sha>/...". Ubuntu's patched tar refuses to extract
through an absolute symlink, failing with "Invalid cross-device link" on
images that link /var/run to /run, so actions never reached the job
container. Extract at the destination with relative entries instead, like
Copy already does.
This is a similar issue to #1128, but for k8s instead of Docker.
I built the image and deployed it to my k8s cluster to verify the fix.

Adds a Kubernetes backend. A `name:kubernetes://image` label runs the job as one pod through the Kubernetes API, with services as containers of the same pod. Step env is exported by a script sent over exec stdin, keeping it out of the pod spec and process arguments, and service env goes into a per-job Secret. Docker actions and container options are rejected. See `docs/kubernetes.md`.
Operators shape job pods with `kubernetes.pod_template`, with per-label `pod_templates` merged in `runs-on` order and a `$services` entry for service containers. The idle cleanup removes pods and Secrets a runner left behind.
The client calls the Kubernetes API directly and runs step commands over `coder/websocket` (same dependency used in gitea) instead of pulling in the heavyweight `kubernetes/client-go`. Includes an e2e test against k3s.
