[Feature Request] Multi-agent session orchestration with inter-session communication

Bug Description
▎ Feature Request: Multi-agent session orchestration (PM agent)

▎ I'd like a parent Claude Code agent that can:
▎ - Send instructions to multiple running child sessions in real-time
▎ - Access child sessions' conversation context and memory without losing them
▎ - Manage multiple projects as a PM-level orchestrator
▎ - Communicate with existing sessions via an external API/command

▎ People are already hacking this together unofficially, but official support would be far more
reliable and unlock real multi-project workflows. The building blocks are there (memory, --resume,
subagents) — what's missing is inter-session communication.
