Fix missing "debug" and "environment" keys in runner context

[kachick]

Fixes #78

• Add validation test
• Update completions test
• Fix them with adding default context

[CRC-Mismatch]

(Sorry for the false-approval, I misclicked 🥴 )

Shouldn't this be "0" by default? 🤔
My reasoning is that it will only be "1" if a workflow is run with a secret/variable ACTIONS_RUNNER_DEBUG set to true in context¹ (or when ticking the "Enable debug logging" checkbox when re-running jobs)...

Thank you for reviewing. 🙏 I referred https://github.com/github/docs/blob/0208d54f08a79b92ba27a010722c87eb327e1c61/data/reusables/actions/runner-debug-description.md?plain=1#L1 for this value, and I understood the debug will be 1 or empty / undefined instead of 0.

I have checked the current ubuntu-24.04 runner behavior in https://github.com/kachick/example-actions-languageservices-78

In normal run

https://github.com/kachick/example-actions-languageservices-78/actions/runs/11745248730/job/32722225773

Run echo "$RUNNER_CONTEXT"
  echo "$RUNNER_CONTEXT"
  shell: /usr/bin/bash -e {0}
  env:
    RUNNER_CONTEXT: {
    "os": "Linux",
    "arch": "X64",
    "name": "GitHub Actions 14",
    "environment": "github-hosted",
    "tool_cache": "/opt/hostedtoolcache",
    "temp": "/home/runner/work/_temp",
    "workspace": "/home/runner/work/example-actions-languageservices-78"
  }
{
  "os": "Linux",
  "arch": "X64",
  "name": "GitHub Actions 14",
  "environment": "github-hosted",
  "tool_cache": "/opt/hostedtoolcache",
  "temp": "/home/runner/work/_temp",
  "workspace": "/home/runner/work/example-actions-languageservices-78"
}

In debug mode

##[debug]Finishing: Dump runner context

So I still guessing debug should never become 0.

However in this test, ACTIONS_RUNNER_DEBUG in repository secrets/variables setting does not change the injected ENV.
It looks only depend on the run is debug mode or not.

And I'm guessing actual source of truth is written in https://github.com/actions/runner/blob/6ef5803f24724b77a8d3599a478d06018da5d7c6/src/Runner.Worker/JobRunner.cs#L155-L158.

                if (jobContext.Global.WriteDebug)
                {
                    jobContext.SetRunnerContext("debug", "1");
                }

Whichever the default value, In my understanding, these values are not actually used in this extension; only the keys are used.

• 👍 If on section is not including pull_request, accessing github.event.pull_request.assignee alerts Context access might be invalid: pull_request.
• 🤔 On the other hand, this runner.debug does not consider whether the runner is actually in debug mode or not.

I have no idea how to realize the polite behavior. 🙇‍♂️
