Add MonitorRegistry for death watch subscriptions. Actors subscribe via
ctx.monitor(target) and receive a Down { addr, reason } message when the
target dies (stop or panic). Supports stacking, demonitor, and automatic
cleanup of dead watcher subscriptions.

Add NameRegistry (String → ActorAddress) to delivery.rs with forward and
reverse maps for O(1) lookup and cleanup. Actors can be spawned with names
via rt.spawn_named() / ctx.spawn_named(), looked up via where_is(), and
names are automatically freed when actors stop or panic.

Adds deterministic tick-based timer scheduling to the actor runtime.
Timers are per-worker (no cross-thread sync) and tick-counted (not
wall-clock), making them suitable for simulation and testing.
API: ctx.send_after_ticks() for one-shot, ctx.send_interval_ticks()
for repeating timers. Timer messages route through the full delivery
system (local pool, cross-worker transfer, and external inboxes).
Fixes over-aggressive interval timer GC that incorrectly removed
timers targeting inboxes and cross-worker actors.

Add actor lifecycle hooks and two-mode graceful stop mechanism:
- ActorInterface::on_start() called once before first message (panic = poison)
- ActorInterface::on_stop() called on graceful stop (NOT on panic - unsafe)
- ctx.stop_self() for immediate self-stop after current message
- runtime.stop_actor() for external stop (PoisonPill semantics, queued)
- Separate stats tracking: stops counter distinct from panics
- 12 new behavioral tests, 82 total passing

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.
