- Replace heavy RefreshAccountToken with lightweight tryFillProjectID
(loadCodeAssist → onboardUser → fallback), consistent with
Antigravity-Manager's behavior
- Add sync.Map cooldown/dedup (60s) to prevent repeated fill attempts
- Add fallback project_id "bamboo-precept-lgxtn" matching AM
- Extract mergeCredentials helper to eliminate duplication
- Use slog structured logging instead of log.Printf
- Fix time.Sleep in OnboardUser to context-aware select
- Fix strings.NewReader(string(bodyBytes)) → bytes.NewReader(bodyBytes)
- Remove redundant tc := tc in test (Go 1.22+)
- Add nil guard in persistProjectID for test safety
- GetAccessToken: add upstream branch to read api_key from credentials
- shouldTriggerAntigravitySmartRetry: relax check from IsOAuth to Platform-based
- isModelSupportedByAccount/WithContext: replace IsAntigravityModelSupported
whitelist with mapAntigravityModel for unified scheduling/forwarding logic
- mapAntigravityModel: fix edge case where wildcard target equals request model
- Update tests for new behavior and add custom model_mapping test cases
