Use standard runners for issue triage framework jobs

[nagilson]

Summary

• keep roles: all; non-maintainer issue authors are already authorized
• run gh-aw framework jobs on ubuntu-latest instead of ubuntu-slim
• avoid the single-CPU runner's hard 15-minute job timeout canceling triage before any step executes

Root cause

The workflow did trigger for non-maintainer issue #55639 as actor damienhoneyford, but its pre_activation job never acquired a runner and was canceled after exactly 15 minutes with runner_id: 0, zero steps, and zero billable milliseconds:

https://github.com/dotnet/sdk/actions/runs/31119268940

GitHub documents that ubuntu-slim has a hard 15-minute job timeout:

https://docs.github.com/en/actions/reference/runners/github-hosted-runners#single-cpu-runners

The gh-aw documentation says roles: all allows any user and runs-on-slim controls generated framework jobs:

https://github.github.com/gh-aw/reference/triggers/
https://github.github.com/gh-aw/reference/frontmatter/

A separate fork test confirms the existing permissions work for a non-maintainer. Issue nagilson/sdk#128, opened by Toxitricity with author_association: NONE, automatically triggered and completed successfully:

Validation

gh aw compile issue-triage --strict completed with zero errors and zero warnings.

Fixes #55652

Live branch-ref validation: https://github.com/nagilson/sdk/actions/runs/31133889908 assigned pre_activation to the requested ubuntu-latest label and completed that job successfully.

Pull request overview

This PR adjusts the issue-triage agentic workflow configuration to avoid the hard 15-minute timeout associated with ubuntu-slim runners by switching generated framework jobs to run on standard GitHub-hosted runners (ubuntu-latest). This is intended to prevent triage from being cancelled due to runner allocation delays, especially for non-maintainer issue authors.

Changes:

• Add runs-on-slim: ubuntu-latest to the issue-triage workflow frontmatter to override the runner label used for generated framework jobs.
• Regenerate the compiled workflow (issue-triage.lock.yml) so affected jobs now use runs-on: ubuntu-latest instead of ubuntu-slim.

• The README claims the ubuntu-slim 15-minute limit includes time spent waiting for runner allocation. GitHub’s normal job timeouts don’t count queued time, so this wording is likely inaccurate; better to describe the observed behavior (jobs can be canceled before steps start if allocation is delayed) without asserting how the limit is computed.

The shared `pat_pool` job runs on `ubuntu-latest`. Do not change it to `ubuntu-slim`, which has a hard 15-minute job limit that includes time spent waiting for runner allocation.
