Introduces direct @ prompt syntax with interactive autocomplete, adds Vim count multipliers across Normal and Visual modes, enhances headless execution lifecycle and task timeout handling, and fixes file-lock concurrency issues in conversation history databases along with streaming response stability fixes.

Added @ prompt syntax to send a message directly to a subagent conversation, with autocomplete listing running and completed subagents.
Added Vim numeric count multipliers so counts apply to operators, motions, and actions in Normal and Visual modes, including 3dw, 2d3w, 3dd, 3x, 3rX, 3p, 3u, [count]G/gg/$, and counted text objects such as 2di(.
Improved GEMINI_API_KEY sessions to reduce behavior discrepancies with the non-API-key sign-in path.
Improved the artifact viewer to show a Left/Right pan hint in the footer when a wide diagram overflows the window.
Improved /rewind to show a relative timestamp for each step and to focus the most recent step when the panel opens.
Improved command allow-listing suggestions to recognize jj config and jj op subcommands when offering to always allow a command.
Fixed headless (-p / --prompt) runs leaving daemon background processes running after exit, which could hang scripts reading the CLI's output until end-of-file; daemon processes now terminate when the run ends.
Fixed headless (-p / --prompt) runs cancelling still-running background tasks about 5 seconds after the agent went idle; runs now wait for background tasks until the --print-timeout deadline, up to a 30-minute cap.
Fixed a conversation-history database corruption risk where checking the database file for write access could silently drop file locks held by concurrent CLI processes on the same file.
Fixed context compaction failing when the tool configuration used for compaction checkpoints was rejected in certain scenarios.
Fixed a backend crash when a streamed model response chunk arrived without its response envelope, which terminated the session with connection errors.
Fixed markdown table column alignment when a table cell contains file links that wrap across lines.
Fixed markdown file links to code symbols dropping their display text and rendering the raw path instead.
Fixed incomplete enterprise sign-ins (for example closing the browser window before finishing license or project selection) leaving behind a stuck partial credential; such credentials are now cleared automatically so sign-in can be retried cleanly.
Fixed the browser companion page title to read Antigravity CLI instead of Antigravity Cli.
