Prerelease: no

Release notes:

New Features

• Added a built-in Google Cloud Vertex AI provider, configured with model_provider = "gcp". (#56265)
• Added GPT-6.1 Terra to the model catalogs. (#57337)
• Added a repository filter to the session picker and directory grouping to the agent command center, making it easier to navigate sessions across linked worktrees. (#56308)
• Added experimental attached thread forks to the app-server API. (#56351)
• Enabled reasoning effort changes during a conversation by default for supported models. (#56163)
• Enabled memory v2 by default for fresh profiles and added support for importing external-agent memories into it. (#56211, #56414)

Bug Fixes

• Fixed fresh TUI sessions to honor the server’s default approval reviewer when no explicit override is provided. (#56090)
• Kept TUI preferences editable and immediately applicable when execution settings are invalid. (#56091)
• Cancelled remote MCP tool requests when their local response futures are dropped. (#56132)
• Prevented queued agent messages from restarting work after an interrupt or a switch to Plan mode. (#56330)
• Stopped retrying when a provider reports that a model was not found, preserving its error message. (#56445)
• Closed a marketplace URL validation gap that could allow Git to connect to a different host than the one checked against allowed patterns. (#56263)
