Pull request overview
Scopes the Helix Job Monitor feature to the main eng/pipelines/runtime.yml pipeline by disabling it by default in shared pipeline variables and explicitly opting in from the runtime pipeline definition.
Changes:
- Default
enableHelixJobMonitortofalseineng/pipelines/common/variables.yml. - Explicitly set
enableHelixJobMonitor: trueineng/pipelines/runtime.ymlso the runtime pipeline continues to include the monitor job and passuseHelixMonitorthrough its Helix template invocations.

| eng/pipelines/runtime.yml | Opts the runtime pipeline into Helix Job Monitor explicitly via a local variable override. |
| eng/pipelines/common/variables.yml | Changes the shared default for enableHelixJobMonitor to false so other pipelines don’t implicitly enable monitoring behavior. |

is there a plan to enable it back on other pipelines, e.g. |

@mmitche build monitor seems to be holding up this PR too (at least for the next hour or so, it seems to timeout after 6+ hours) |

We should also enable it very soon in the JitStress pipelines that run a lot of scenarios. We've already taken a change that depends on the job monitor for those pipelines to not wait on jobs to finish before submitting more jobs. |

/ba-g runtime and runtime-diagnostics pipeline failures are unrelated to this change |

## Summary - default `enableHelixJobMonitor` to `false` in the shared pipeline variables - explicitly enable it in `eng/pipelines/runtime.yml` - preserve the standalone monitor job and fire-and-forget submissions only for the runtime pipeline ## Motivation The original rollout in dotnet#129690 intended to enable the Helix Job Monitor only for the runtime pipeline. However, the switch was set to `true` in the shared variables template imported by other pipelines. This caused standalone pipelines such as [`runtime-coreclr superpmi-collect` build 3043381](https://dev.azure.com/dnceng/internal/_build/results?buildId=3043381&view=results) to configure Helix submissions for out-of-band monitoring without adding a monitor job. Those submissions returned after submission rather than waiting for completion. Defaulting the shared switch off and opting in from `runtime.yml` keeps the complete feature scoped to its intended pipeline. ## Validation - `git diff --check` - verified `enableHelixJobMonitor` is enabled only by `eng/pipelines/runtime.yml` > [!NOTE] > This pull request description was generated with GitHub Copilot.
