Supervisor pattern

Status: planned/not implemented as a named framework pattern.

LiveKit's docs describe supervisor-style orchestration as a way to coordinate specialized agents. rtp-agent has pieces that can support handoff behavior, but it does not currently expose a named supervisor framework.

Use the existing primitives instead:

• AgentSession.UpdateAgent can switch the active agent.
• RunResult records agent handoff events.
• core/beta/workflows contains specific workflow helpers.

Do not document a production supervisor pattern until the repository has a source-backed package or example that defines the pattern and tests its behavior.

Evidence:

• app/app.go includes a handoff workflow entry.
• No source package named supervisor or full supervisor orchestration exists under core/agent or core/beta/workflows.
