Implement nudge: send message to active agent from ClawView

[jakzilla]

Feature Spec

Allow the user to send a brief nudge message to an active agent directly from the ClawView popover.

UI

• A Nudge button on each active agent card (only visible when agent status == 'active')
• Tapping it sends the default nudge message to the agent
• A confirmation toast appears: "Nudged Linus ✓" (2 second auto-dismiss)
• If the request fails: "Nudge failed" toast in red

API (Gateway — must be implemented first)

POST /api/sessions/:agentId/nudge
Body: { "message": "Jack wants to know your status." }
Response: { "ok": true } or { "ok": false, "error": "..." }

The Gateway routes the nudge to the named agent's active session as a new user message.

Default nudge message

"Jack wants to check in — what are you working on right now? Brief update please."

Blocked by

• Gateway must implement POST /api/sessions/:agentId/nudge endpoint

Implementation notes

• Button: small secondary style, bottom-right of agent card, only shown for active agents
• Use async/await with a 5s timeout; show error toast if timeout exceeded
• No confirmation dialog — tap once to nudge (low stakes action)
