v0.79.0-alpha

Added

• Images a generation tool saves to disk show in the chat gallery, including images from an image-generator subagent.
• Each ACP agent keeps its own default model, effort, and permission mode. A session that has not chosen yet uses that agent's default.
• Antigravity keeps a turn open while a subagent is still running after the prompt ends, and answers elicitation through the question card.
• Offline hosts share one folded group. Project focus and the unfocused multi-host list give leftover pane height to long session lists. The 256px cap stays when every open environment already overflows it.
• Sidebar groups ease open and closed over 120ms. Heavy lists unmount after the close. Drafts keep their height animation.

Changed

• Antigravity uses the agy CLI installed on the machine. Enable, readiness, and login resolve it on PATH or the known bin directories, and a saved agy_acp_server command moves onto that CLI.

Fixed

• Streaming reasoning no longer fades in. Markdown still fades each new commit.
• Antigravity usage reads the active Cloud Code quota endpoint, and one endpoint's numbers no longer replace the other's.
• Message actions sit above the compact turn rail, so table and diagram toolbars and copy on a user message stay on the markdown edge.
• Pending sends, MCP startup, and harness retries share one footer. A local send does not show the remote sending label.
• A queued message that joins a live reply clears the sending state. Steering that continues the current reply does not show a second pending reply. (#174)
• Mentions resolve files, apps, and catalogs on the session's own host. A remote pane does not grant an app on the machine in front. (#172)
