Thomas Kosiewski 12f87acad6 feat(site): add terminal panel to chat sidebar (#23231)
## Add terminal panel to chat sidebar

Extract the reusable terminal runtime from `TerminalPage` into
`modules/terminal/` and wire it into the agents chat right sidebar as a
new **Terminal** tab.

### Changes

- **`modules/terminal/WorkspaceTerminal.tsx`** — Shared xterm +
websocket terminal component (container-sized, no route dependency)
- **`modules/terminal/WorkspaceTerminalAlerts.tsx`** — Moved from
`TerminalPage/` to shared module
- **`pages/AgentsPage/TerminalPanel.tsx`** — Sidebar wrapper around
`WorkspaceTerminal`
- **`pages/AgentsPage/AgentDetailView.tsx`** — Terminal tab added (gated
on `hasWorkspace`)
- **`pages/TerminalPage/TerminalPage.tsx`** — Slimmed to page-shell
using shared component

### Demo

### Behavior

- Terminal tab appears only when the chat has a workspace with a
connected agent
- Connects via the existing workspace agent PTY websocket
- Resizes correctly on panel width changes, expand/collapse, and
viewport resize
- `fitAddon.fit()` guarded against pre-renderer crashes (fixes proxy
access)
- Tab switching unmounts/remounts cleanly (reconnects via session token)
- No changes to Git or Desktop panel behavior
