Rewrite to make the runtime more cache aware and amenable to load balancing across workers.

Rewrite to make the runtime more cache aware and amenable to load balancing across workers.

Ran through a few passes of the 'happy path' with the debugger, ran flamegraph analysis: we
are very much overdoing the atomic ring buffer channels. They may be fast for concurrency
across threads, but we don't necessarily need that for every occasion.
Our first implementation is incredibly slow, and failed to scale with increased threads. In order to fix this, we
are implementing cache-aware batching of message processing, and an epoch-based actor rebalancing using shard pools.

In the middle of a vibe-coded infra change. Modularizing the components into APIs amenable to lots of testing and optimization.
Fleshing out the architecture before abstracting into components amenable to api-based test harnesses for fuzz and optimization working loops.
