Fix CI Cleaner: Add repo checkout and noop handling for passing CI

[Copilot]

CI Cleaner workflow was succeeding but producing no safe outputs, triggering false failure issues. Root cause: check_ci_status job silently failed (couldn't run gh CLI without repo checkout), and agent lacked instructions to call noop when CI passes.

Changes

check_ci_status job:

• Added actions/checkout step before gh run list command
• Added contents: read permission

Agent instructions:

• Added explicit "Check CI Status First" section
• When ci_status: success, call noop tool and exit immediately
• Applied to both .github/workflows/hourly-ci-cleaner.md prompt and .github/agents/ci-cleaner.agent.md

Context

The workflow's if: needs.check_ci_status.outputs.ci_needs_fix == 'true' gate wasn't working because the check job failed with:

failed to determine base repo: fatal: not a git repository (or any of the parent directories): .git

This left ci_needs_fix undefined, causing unpredictable behavior. Even when it worked, the agent never produced safe outputs when CI was passing.
