feat: managed agents follow-ups - safety, protocol consistency, CLI parity (fixes #1426 #1429 #1430)

- Add ManagedSandboxRequired exception and host_packages_ok safety flag
- Wire compute provider to package installation with sandbox enforcement
- Add unified SessionInfo schema with lazy ManagedBackendProtocol re-export
- Add missing CLI delete/update commands with confirmation prompts
- Maintain protocol-driven architecture and backward compatibility
