GUI: add Ctrl+B2 'Send to' menu for cross-agent messaging

- Ctrl+middle-click on selection opens cascading menu
- Session list → Agent list navigation
- ollie.submitTo(sessionId, agentId, prompt) via 9P
- Fixed nested Instantiator scope with explicit property capture
- Theme colors for ProcManager/PeerManager windows
- Kate plugin uses 'default' session instead of 'kate'
