Antigravity CLI 1.2.12

[Improvements] Improved scrolling in the full-screen view: bursts of mouse-wheel or trackpad events are now coalesced before redrawing, which cuts CPU use and reduces scroll lag in long conversations and the artifact viewer.

[Improvements] Improved GEMINI_API_KEY sessions to stop immediately when the Gemini API reports an exhausted daily quota, a project or billing-account spend cap, or depleted prepaid credits, instead of spending several minutes on retries that cannot succeed; short-lived per-minute rate limits are still retried.

[Fixes] Fixed resuming a long conversation in medium or low verbosity taking many seconds and lagging while history replayed: earlier tool groups now appear already finished instead of each re-animating, and keys pressed during the replay no longer refresh a half-loaded transcript.

[Fixes] Fixed the terminal or tab title changing to a string like Ga=q,f=32,... every time the CLI starts inside GNU screen, tmux (including iTerm2 tmux -CC tabs), or Zellij; the CLI no longer sends its image-support probe through a multiplexer, and CLI_GRAPHICS=kitty still forces image mode.

[Fixes] Fixed Vim mode ignoring non-ASCII characters such as é or 中 after r, f, F, t and T, fv and fV in Visual mode leaving Visual mode instead of extending the selection, and D, C, or Visual ~/u/U recording an empty undo step and clearing redo history when they changed nothing.
