A maintenance release that keeps the runtime current and tightens consistency across surfaces. The Claude Agent SDK moves to 0.3.177, the Obsidian model and subagent catalog now derives from the SDK exactly like the server does, and four fixes clear up worktree dev ports, slash-command dispatch, session titles, and canvas scrolling.

Highlights

SDK 0.3.177 - The Claude Agent SDK upgrade restores background-agent and MCP task state on session resume, so long-running agents pick up exactly where they left off after a reconnect.
One model catalog, every surface - The Obsidian (DirectTransport) model and subagent lists now derive from the SDK through the same path the server's /api/models route uses. No more hand-maintained list that drifts — when a model is added or withdrawn, every surface reflects it identically.
Slash commands work over chat - Commands like /compact now dispatch as bare prompts so the CLI parses them correctly (DOR-107).
