#cmux 0.64.8: Antigravity CLI, Grok Vault Resume, CLI Window Targeting, Browser Screenshots

Antigravity CLI Integration. Antigravity joins the supported coding-agent lineup with hook notifications, task manager attribution, and Vault session restore, the same way Claude, Codex, Gemini, and Grok already work in cmux.

Native Grok Vault Resume. Grok sessions can now be resumed natively from Vault. cmux parses registered Grok transcripts by layout, deduplicates sessions across shell-Grok homes, and quotes built-in resume commands so they round-trip cleanly.

CLI Window Targeting. cmux CLI commands now accept `--window` to scope workspace, pane, surface, SSH, VM, notifications, tree, and top flows to a specific window. Refs resolve inside the targeted window, and cross-window pane handles are rejected before they mutate state.

Browser Screenshot Clipboard Actions. Capture a screenshot of the current browser pane and copy it straight to the clipboard, ready to paste into an agent conversation or notes.

Browser Webviews Kept Alive. Reverts the 0.64.7 default of discarding hidden browser webview renderers. Switching back to a hidden browser pane now resumes instantly without reloading. The discard behavior remains available as an opt-in setting.

Bug Fixes. Fixes for minimal-mode pane tabs moving the window when dragged, Option dead-key accent composition (Option+n then a now commits "ã"), equalize splits with 3+ panes, Quick Look preview crashes, git index.lock polling, theme override paths leaking from channel builds, sidebar overlay contrast, terminal scheme synchronization on theme reload, restored unread badges, transparent terminal hosting, browser navigation race conditions, and session search ripgrep cancellation crashes.
