- Around line 794-799: Update the managed Antigravity error handling around
fetch_with_managed_agy so readiness/startup failures fall through to the
offline-conversation path like AGY_NOT_FOUND_MESSAGE, while AuthRequired errors
and other actionable provider errors still propagate. Add a short-lived backoff
for recent non-auth readiness failures so repeated fetch_usage refreshes do not
relaunch agy during the cooldown.
In `@rust/src/providers/antigravity/tests.rs`:
- Around line 239-250: Update the expected path assertions in the test to
construct both values with PathBuf::join from the same roots supplied to
agy_binary_candidates, preserving the platform-specific executable name for the
local bin candidate.

The managed agy lifecycle runs blocking work on tokio worker threads. Port enumeration and process teardown are synchronous operations placed directly in async code, so each managed fetch can stall the shared runtime.

Sign-in failures (AuthRequired) keep surfacing, but non-auth local-probe and managed agy start failures now fall through to the offline conversation-history snapshot instead of replacing it with a hard error. Build the agy candidate-path test expectations with PathBuf::join so the test passes on non-Windows hosts, and note IPv6 listener discovery as an accepted follow-up.

Summary
Make Antigravity quota refresh work when the desktop app is closed by launching a short-lived, task-owned
agysession in a hidden PTY.The provider still prefers an existing Antigravity language server or user-owned
agy. Only the fallback process is managed, its terminal output is drained without logging, readiness is bounded, and the exact owned child is stopped and reaped after the fetch. The current offline conversation-history snapshot remains available when neither Antigravity noragyis installed.This brings the Windows behavior in line with the upstream Antigravity fallback.
