- Updated `executeSearch` to read `providers.antigravityEndpoint` once and catch uninitialized-settings errors, so web search fallback no longer aborts before any provider runs. - Added missing `Vision` and `Git` entries to `TAB_GROUPS` so those new settings now render in their intended setting-section groups. - Adjusted context and idle-compaction tests to wait for prompt-in-flight transitions and provide `getContextUsage` for deterministic snapshots during pending turns.
