alt-glitch 31e59b9441 feat: setup agent can search the catalog and install plugins and skills through the approval card
The setup profile's `setup` toolset was empty. It now carries one tool, manage_catalog:

- search: catalog plugins (the Plugins tab's live catalog resolver) and hub skills, with
  whether each is already installed in the default profile. Read-only.
- install: opens the same connection operation manage_connections opens, with rows of kind
  plugin / skill. Nothing installs until the user approves a row. An approved row installs
  into `default` (or the profile the Advanced modal named) through dashboard_install_plugin /
  the hub's headless install, so the catalog pin, kill list, security scan and live
  activation (#119644) are the host's. The row settles with the live MCP tool names and the
  plugin's skill.

The model sends catalog ids and an action only; every other key is refused before anything
runs. An unknown id or a plugin this OS cannot run is drawn failed with the installer's own
text. Anywhere a catalog card cannot be drawn (TUI, CLI, messaging, registry dispatch) the
result is the `hermes plugins install` / `hermes skills install` pointer.

- contract: plugin/skill targets follow the MCP transitions.
- run.apply_answer / reissue route a card answer to the module that owns the operation.
- tool_search: `setup` joins the direct-surface toolsets, so the guide's one tool is never
  deferred behind tool_search.
- docs: tools reference, toolsets reference, plugin catalog page.
