Dotta 1b74561fea ci(runner): route paid matrix to AWS fleet (#12765)
## Thinking Path

> - Paperclip manages AI agents that perform work.
> - The paid runner matrix verifies complete runner behavior with real
providers.
> - Each matrix job currently repeats work on GitHub-hosted runners.
> - Paperclip has an ephemeral AWS runner fleet for trusted workflows.
> - The paid workflow needs a reviewed and fail-closed route to that
fleet.
> - This pull request adds that route and keeps the existing hosted
runner as the disabled-state fallback.
> - The benefit is faster paid campaigns with the same actor,
environment, and secret boundaries.

## Linked Issues or Issue Description

**What happened?**

The Runner Full-Stack E2E workflow always uses `ubuntu-latest-m`. It
limits the matrix to 57 parallel jobs. The repository AWS fleet can run
100 ephemeral jobs, but the paid workflow cannot select it.

**Expected behavior**

An explicit repository flag must select the reviewed AWS fleet label. A
missing or invalid flag must keep the existing hosted runner. The
workflow must authorize the stable actor identity before it routes any
paid job.

**Steps to reproduce**

1. Dispatch the Runner Full-Stack E2E workflow from `master`.
2. Inspect a paid matrix job.
3. Observe that the job requests `ubuntu-latest-m` even when the AWS
fleet should be used.

**Deployment mode**

GitHub Actions paid runner campaign.

## What Changed

- Add a fail-closed `RUNNER_E2E_AWS_ENABLED` switch.
- Select only the reviewed AWS fleet label or the existing hosted label.
- Permit up to 100 parallel jobs in AWS mode.
- Keep the hosted-runner limit at 57.
- Reauthorize paid execution before checkout and provider access.
- Stop paid checkouts from storing GitHub credentials.
- Cancel superseded validation-ref campaigns while preserving `master`
audit runs.
- Add workflow policy checks and operator documentation.

## Verification

- `git diff --check`
- `actionlint -ignore SC2129
.github/workflows/runner-full-stack-e2e.yml`
- The organization runner group permits this workflow only from
`refs/heads/master`.
- The repository AWS switch remains disabled until this pull request is
merged and a one-cell probe succeeds.

## Risks

- A wrong fleet policy can leave jobs queued. The disabled state keeps
the existing hosted runner.
- The AWS fleet uses paid compute. The workflow validates a configured
maximum of 100 jobs.
- The runner group, actor allowlist, and paid environment remain
separate enforcement layers.

discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

OpenAI Codex based on GPT-5 with agentic reasoning, repository
inspection, code editing, Git, GitHub API coordination, and static
workflow analysis. The exact deployed model identifier and
context-window size are not exposed to this task.
