Fixes #10341
Clean cherry-pick of the value commit from #10879 (by @adevwithpurpose), whose branch had accumulated ~100 commits of already-merged release history and could not be diffed directly (GitHub: diff too large). The other 3 commits ahead of the release tip on that branch were duplicates of #10834 (compression) and #10800 (conversations), already merged separately, and an already-shipped cherry-pick of upstream #10709. This PR carries only the genuinely new antigravity fix, unmodified, with the original author's commit preserved.
Summary
When using Antigravity/AGY with Gemini 3.7 Flash tiers (
gemini-3.7-flash-high,gemini-3.7-flash-medium,gemini-3.7-flash-low, orgemini-3.7-flash), Google's internal Cloud Code endpoint (streamGenerateContent) expects the underlying model idgemini-3.7-flash-tieredinside the request envelope. Sending raw tier strings directly causes Google's endpoint to reject the request or time out after 30s.Changes
