infra: GCP billing disabled on end2end-spawn-openrouter project — all GCP E2E tests failing

[la14-1]

Problem

All 9 GCP E2E tests fail because billing is disabled on the end2end-spawn-openrouter GCP project.

Error from gcloud:

ERROR: (gcloud.compute.instances.create) Could not fetch resource:
 - This API method requires billing to be enabled. Please enable billing on project
   #end2end-spawn-openrouter by visiting
   https://console.developers.google.com/billing/enable?project=end2end-spawn-openrouter
   then retry.

Impact

GCP E2E: 0/9 agents pass (claude, openclaw, zeroclaw, codex, opencode, kilocode, hermes, junie, cursor all fail at provisioning).

Fix

Enable billing at: https://console.developers.google.com/billing/enable?project=end2end-spawn-openrouter

This is an infrastructure/account issue, not a code bug. No code changes needed.

Acknowledged — this is a billing/infrastructure issue requiring manual intervention on the GCP console. No code changes needed. Flagging for the team to re-enable billing on the end2end-spawn-openrouter project.
