Summary

Test in GCE VM provisions a real GPU-backed GCE instance per PR run and has been flaking heavily today on shared infra issues unrelated to code changes: GPU zone capacity stockouts across multiple regions, serial-port-output fetch errors, and leftover-instance naming collisions from prior failed runs. It's also a required status check, so every flake blocks merging regardless of content.

The workflow already carried (broken) logic to skip itself on dependency-bump PR titles (chore(deps)/fix(deps)), but that never matched our actual PR titles, so it kept running and repeatedly blocking merges today.

Switches the trigger to workflow_dispatch-only so it can still be run manually (or wired into a release/nightly job later) without gating every PR on GCE GPU capacity availability.

Note: this PR alone won't fully unblock things — Test in GCE VM is also in the branch ruleset's required-status-checks list, so it'll need to be removed there too (same fix as the earlier stale CodeQL check), otherwise a disabled job just leaves the check permanently pending.

Test plan

  • YAML is valid (workflow won't fire on pull_request anymore)

This job provisions a real GPU-backed GCE instance per PR run, and has
been flaking heavily on shared infra issues unrelated to code changes:
GPU zone capacity stockouts across multiple regions, serial-port-output
fetch errors, and leftover-instance naming collisions from prior failed
runs. It also already carried (broken) logic to skip itself on
dependency-bump PR titles, which never matched our actual titles, so it
kept running and blocking merges on every dependency PR.

Switch it to workflow_dispatch-only so it can still be run manually or
wired into a release/nightly job later, without gating every PR on GCE
capacity availability.
