Add spawn_restartable(actor, factory, max_restarts) to Runtime and Ctx.
On panic, the actor is recreated using the factory with fresh state and
cleared mailbox. After max_restarts exhausted, permanently poisoned.
AnyActor::try_restart() trait method with backward-compatible default.
Factory stored as Arc<dyn Fn() -> A + Send + Sync> — safe to read after
catch_unwind since factory fields are never touched by handle_any.

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.
