refactor(runtime): own communication and social state

Construct chat history, negotiated channels, friends, squelch, and reply targets in one presentation-independent Runtime owner. Make live routing, retained UI, devtools, and current-runtime projections borrow the exact instances, preserve reconnect reset semantics, and publish failure-isolated reentrant-safe chat commits.
