This has been fixed and tested

Greptile Overview

Greptile Summary

This PR updates the Google Antigravity integration to satisfy server-side client/version checks by changing the request metadata sent to Antigravity endpoints. Concretely:

The Antigravity OAuth extension now sends a new Client-Metadata payload when calling loadCodeAssist to discover the user’s project.
The Pi embedded runner injects Antigravity-specific headers (User-Agent, X-Goog-Api-Client, Client-Metadata) via the stream wrapper so model calls present the expected client identity.
The Antigravity usage fetcher (provider-usage.fetch.antigravity.ts) updates its metadata payload for loadCodeAssist to the same new format.

Overall, this fits into the codebase’s provider plumbing by aligning the auth/usage/model-call surfaces to send consistent identifying headers/metadata to Google Antigravity APIs.

Confidence Score: 3/5

This PR is likely safe to merge, but there is one behavioral risk around header merging that can undermine the intended fix.
Changes are localized and straightforward, but the new Antigravity header patch can be overwritten by caller-provided headers due to merge order, which could reintroduce the version-check failure. The remaining issues are maintainability concerns (duplicated hard-coded metadata).

[P1] Antigravity metadata is duplicated + hard-coded.

This file defines a METADATA object with the same hard-coded ideVersion/os values also used in other Antigravity call sites (e.g. auth extension and stream header patch). If these values need updating, it’s easy for one place to drift and cause inconsistent behavior across endpoints. Consider centralizing the Antigravity client metadata (or at least exporting a shared constant) so all requests use identical metadata.

This file defines a `METADATA` object with the same hard-coded `ideVersion`/`os` values also used in other Antigravity call sites (e.g. auth extension and stream header patch). If these values need updating, it’s easy for one place to drift and cause inconsistent behavior across endpoints. Consider centralizing the Antigravity client metadata (or at least exporting a shared constant) so all requests use identical metadata. How can I resolve this? If you propose a fix, please make it concise.

[P0] options?.headers currently overrides the Antigravity version/metadata patch.

In wrappedStreamFn, you build headers as { ...streamParams.headers, ...options?.headers }. Since options are provided by callers, any existing options.headers (even empty defaults) will overwrite the User-Agent/Client-Metadata you set for provider === "google-antigravity", which can reintroduce the exact server-side version check failure this PR is trying to fix. Consider reversing the merge order for Antigravity (or only force-set the specific header keys after the merge) so the required headers can’t be clobbered by caller defaults.

[P1] Metadata/version headers are hard-coded and OS-specific.

fetchProjectId sends Client-Metadata with ideVersion: "1.15.8" and os: "windows" unconditionally. If the upstream service changes expected versions again, or if their checks validate OS/UA consistency, this can break for non-Windows clients and force another code change. Consider deriving os from process.platform (and keeping the version in a single shared constant) so Antigravity calls stay consistent across platforms and are easier to update in one place.
