v3.26.0

Added

• (agent-platform) Show workspace setup notices as turn status, not as the agent's reply by @marians — In a session started in a workspace, a setup notice such as Workspace setup: 3 repositories not updated shows as a status alert above the agent's answer, with git's output folded under Technical details, instead of reading as the agent's reply.
• (agent-platform) Show an MCP server's sign-in the session waits on, and continue once signed in by @QuentinBisson — When an agent on a runtime such as Claude Code or Codex needs your sign-in to a connector, the session shows a sign-in card with Sign in ↗ and Not now, and the agent continues by itself once you've signed in. Needs muster 5.53.0 or later.
