Add network partition, asymmetric partition, and message loss simulation
to the distribution test harness. 15 new behavioral tests covering
split-brain, cascading failure, seed node death, rapid churn, 50-node
clusters, and actor resolution under partition.
Research notes from studying FoundationDB DST, Hashicorp memberlist,
Antithesis, TigerBeetle VOPR, Turmoil/MadSim, and Jepsen nemeses.

Runtime dashboard now features a TUI option and an interface for LLM tool use. Removed some bloat from stats collecting and replaced with a hook function to dump runtime stats into.
Adds some basic benchmarking, stress tests. They still need to be properly examined to ensure they are testing the correct properties, but fit for "good enough". Implements the HybridChannel type, which features a channel buffer that can withstand overflows. It does so by providing a dequeue behind a mutex. Without overflow, will push messages into the lock free ArrayQueue implemented by crossbeam_queue; when that buffer fills, will use the locking portion provided by the Mutex<VecDequeue>.
In the future we can even further optimize this, perhaps with some linked list implementations of lock-free channels, but, like the benchmarks, this fits the "good enough" bar for now.
Did not like the requirement of a tokio runtime and async/await. Rewrote
to use lock free queues (`crossbeam_queue::ArrayQueue`) as the basic
primitive to enable a runtime consisting of many pseudo-processes that
can pass messages to each other.
