Agents pane: CLI-only MCP, yaak mcp --http, and plugin deprecation

[gschier]

The agent story becomes one sentence: install the Yaak CLI, and every agent talks to it.

• The app no longer hosts an MCP server. mcp_ext.rs, its token, and the port toast are gone; the mcp_server_enabled column stays in the database, unread.
• yaak mcp --http serves the same tools over HTTP on 127.0.0.1 with --port (default 64343) and --token; without a token it generates one and prints it to stderr. For agents that cannot run the host's CLI, such as one inside a container. Two end-to-end tests.
• Settings > Agents is the picker, a CLI status line (re-checked on window focus), and two command blocks. Each is marked done when the agent's config or skills directory already has it, through a new cmd_agent_setup_status command. Claude Code snippets use -s user so the registration is global and detectable. A banner with Uninstall appears while the deprecated @yaak/mcp-server plugin is installed.
• The plugin API reads the registry's new deprecated note (mountain-loop/yaak-web#110) and makes yanked optional. Discover hides deprecated plugins; Installed shows the note with Uninstall. The mcp-server plugin carries the note, a reworded toast, and a README whose Claude Desktop config is yaak mcp with no mcp-remote. Not published yet.

Left for later: rand and yaak-mcp are unused in the app crate's Cargo.toml (lockfile change), and publishing the plugin.

Confidence Score: 5/5

[High impact] The PR appears safe to merge, with non-blocking gaps in setup detection and deprecation warnings.

Findings

1.  Older plugins hide deprecation warnings ▶
2.  VS Code setup looks incomplete ▶
3.  Multiline Codex arguments go undetected ▶

Summary

The PR moves agent connections to the CLI and adds yaak mcp --http.

• The Yaak CLI serves MCP tools over stdio or HTTP.
• Settings > Agents shows setup commands and marks steps it detects.
• Deprecated plugins are hidden from search and come with replacement guidance.
