pages/agents held the roster page, the terminal page and every component under them. It keeps the two pages; the components move to src/agent, by concern: roster (card, wanted menu, actions), detail (panel body, dialog, inference, linked accounts, link menu) and terminal (preview, input, subagents, stream hooks, favicon), with the shared row type and icon at the top. Moves and import rewrites only.
The agent detail panel shows the model and effort an agent runs on with
where each comes from, plus the swarm's subagent model list. An edit
dialog sets the swarm value (PUT) and a clear action removes it (DELETE).
Reads the configured/effective view, and shows the stored values alone
until an agent has reported what it runs on.
