Gud Boi 643e1c861b Complete IPC frames before sender cancellation
Cancellation inside `send_all()` can publish a partial frame. Closing
the actor-wide stream preserved framing but destroyed every context
on the channel and replaced primary errors with `TransportClosed`.

Deats,
- shield complete frame publication, then deliver pending
  cancellation
- keep the shared channel reusable after context-local cancellation
- absorb transport closure while reporting an unshippable overrun
- cover mid-frame cancellation and failed overrun error shipment

This deliberately defers cancellation until the current frame write
resolves; channel teardown remains the fallback for broken peers.
