feat(gui): handle empty sessions in ollie-gui 

- getAgents(): filter out 'new' (agent creation file), return empty list
- setActiveSessionId(): skip agent init when no agents exist
- submit/interrupt/kill/streams: guard against empty m_agentId
- prompt input: disable when no agent, show 'No agent' placeholder
