/**
* `AgentsPanel` — feature component for the agents panel (L6).
*
* Pure presentation: all behaviour comes from {@link useAgents}. Styled with
* `@/shared` design system tokens; no inline styles, no classes invented outside
* the theme.
*
* When the user clicks Launch, an agent terminal is mounted below the agent
* list using a {@link TerminalView} with a custom `open` prop that delegates
* to `agent.launchAgent`. A Stop button unmounts it.
*
* Feature #3: the create form includes a template selector. Choosing a template
* calls `createAgentFromTemplate`; leaving it at "(none / from scratch)" uses
* the existing `createAgent` path with the selected profile.
