create_agent previously threw on cross-provider inheritance unless an explicit
mode was passed. In practice, sub-agents launched without a mode should run
unattended — keying permissions per sub-agent rarely makes sense. When the
caller is in an unattended mode (Claude bypassPermissions, Codex/OpenCode
full-access, Copilot autopilot) and no mode is requested, default the child
to the target provider's own unattended mode. Non-unattended callers still
require an explicit cross-provider mode, and explicit modes always win.
