[models] antigravity onboardUser done but no project in…

Error message

[models] antigravity onboardUser done but no project in response at ${url} — Google BYOP (user-defined GCP project) required

What it means

Terminal bootstrap condition for Google Bring-Your-Own-Project accounts: onboardUser returned 200 but the body lacked `cloudaicompanionProject`, meaning Google will not auto-create a project for this account tier (standard-tier/personal accounts, tracked in #8491). Detected explicitly so bootstrap fails fast with a clear instruction instead of fabricating a project id that Google would later reject with a delayed 429 RESOURCE_EXHAUSTED.

Solutions

1. Configure a user-defined GCP project (BYOP) for the antigravity connection via the connection settings.
2. Upgrade the Google account tier to one that supports automatic project creation.
3. Document in the provider setup UI that standard-tier accounts must supply their own GCP project.
