Restructures the crate to the SIM_SPEC six-component model (engine, network, host,
bundle, evaluator, scenario) and relocates SIM_SPEC.md into the crate. Adds the SWIM
host adapter wrapping production distribution::swim::SwimNode, the swim codec, a
virtual network model, the scenario loader, an assertion evaluator, deterministic RNG,
property-based tests, and reproduction/smoke/topology scenario TOMLs; drops the
detector/divergence/lint/postproc/spec/runtime modules and prior spec docs.

Appends section 7.7 clarifying that the determinism contracts bind only the
simulator's own components: hidden entropy inside a wrapped production dependency
(allocator state, HashMap RandomState, process-local entropy) is out of scope, and
property tests comparing two independently-allocated wrapped state machines should
not be written.

Six per-component property-test subsections (§4.10 engine, §5.8 network,
§6.4 hosting, §8.4 scenario loader, §9.6 bundle writer, §10.5 assertion
evaluator) written in property-language form. Each names the property the
component must have; how the property is verified is the test author's
call.
These were drafted in conversation but never committed, causing the
boundary check to flag SIM_SPEC.md on iteration 1 of the implementation
loop. Committing now puts them at HEAD so future loop iterations diff
cleanly.

Upgrades iroh/iroh-relay across datastore, distribution, node, and integration,
adapts iroh_driver to the new Endpoint::builder(Minimal).relay_mode(...) API, and
removes the vendored ed25519-dalek patch now that 0.98 resolves the upstream compile
errors. Adds the SIM_SPEC.md simulator MVP spec under pipeline-parallel-inference.

Replaces the generic SimNode/gossip/dashboard framework with a virtual-time
discrete-event engine (priority queue ordered by time/node/fiber/seq), a TOML spec
parser, bundle writer, replay, divergence detector, lint, and postproc, plus the
parity-bar test harness with fixtures and xtask parity-lock tooling. Rewrites
transport identity/crypto and adds the SPEC/TESTING_SPEC/OBSERVABILITY/NORTH_STAR docs.

Structured observability for the iroh/SWIM layer: Aggregator, typed Event/Snapshot
types, Sink (NoopSink default), ProbeScheduler, process stats, and host/iroh/swim
introspection, plus the swactor-diag-collector, -postproc, and -iroh-relay binaries
that assemble and render per-run bundles. Generalizes the pipeline-parallel-inference
example to N stages and adds the topology-planner spec.

Extend the single-GPU example into a two-node pipeline-parallel run that splits llama3.2:1b across two rented vast.ai GPUs and closes the autoregressive decode loop over iroh.
- topology: add linear-chain helpers where each stage derives its neighbours locally from `STAGE`/`NUM_STAGES`, registering `pp-entry`/`pp-exit`/`pp-stage-{i}` SWIM names
- messages: add `StageActivation` (bf16 hidden-state hand-off carrying position/seq_len/is_prefill) and `NextToken` (sampled-token feedback with a `done` flag) that close the autoregressive loop between stage 0 and stage 1
- stage_actor: add `Stage0Actor` (tokenize -> embed_and_forward -> prefill activation; decode_step on each NextToken) and `Stage1Actor` (forward_and_sample -> NextToken back; emit InferenceResponse on EOS/max_tokens)
- vastai: fork the client and add `create_pipeline_instances` (rents one instance per stage, threading `STAGE`/`NUM_STAGES`, best-effort destroys on partial failure) and `destroy_all_instances`
- pp_tinygrad_worker.py: per-stage worker slicing `model.blk[start:end]` in stub and real (GGUF) modes, plus new `pp_gpu_node`/`pp_smoke_run` binaries and ROADMAP/SPEC/TEST_SPEC docs
- reuse: build on the single-GPU example's iroh transport and process bridge unchanged; add actor/codec/topology/integration test suites

Add a complete single-GPU distributed-inference example that rents a vast.ai GPU, boots a worker container, and runs a prompt end-to-end over iroh/SWIM.
- examples/single-gpu-inference: add the `single_gpu_inference` orchestrator binary that starts a local iroh node, waits for the remote gpu-node to register the `"inference"` SWIM name, then sends an `InferenceRequest` and prints the response
- examples/single-gpu-inference: add the `gpu_node` binary that joins the cluster via `SEED_ADDR`, spawns an `InferenceActor` over `tinygrad_worker.py`, and registers the `"inference"` bridge
- inference_actor: bridge swactor messaging to a Python child process via stdin/stdout JSON, with `ProcessBridge`/`RequestBridge` adapters that satisfy the single-`Incoming` actor constraint
- iroh_transport: add `IrohActorTransport` that sends `WireEnvelope`s over iroh QUIC uni-streams (connection-cached against early close), plus wire encode/decode and an inbound drain helper
- vastai: add a vast.ai REST client (`find_offer` with reliability/cuda/geo filters excluding CN, `create_instance`, `wait_for_running`, `destroy_instance`) parameterised by a mockable `base_url`
- worker/docs/tests: ship `tinygrad_worker.py`/`echo_worker.py` (newline-JSON, `--stub`/`--model` defaulting to llama3.2:1b), a Dockerfile, Makefile, SPEC, and actor/codec/cluster/integration/vastai test suites

Remove co-dependencies for different modules found in `crates` and migrate the development history to a new repository. The docs were stale, and largely not getting used, so simply deleted for now. When code stabilizes more, they will become useful again.

Crates continued to grow in number, but most are still quite small and feature specific. This refactor consolidates them.

Add a Python getting-started Jupyter notebook and reorganize the Python examples under examples/python/.
- examples/python/getting_started.ipynb: add notebook demonstrating the single-threaded tick loop (`spawn`/`send`/`tick`/`inbox`/`try_recv`) and the multi-threaded path via `RuntimeConfig` + `rt.run()`/`handle.shutdown()`
- examples/: relocate `hello_async.py` and `hello_single_thread.py` under `examples/python/`
- pyproject.toml: add a `dev` dependency group containing jupyter and ipykernel
- uv.lock: regenerate the lockfile for the new dev dependencies (2452 lines)

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.

Introduce a typed `ActorRequestSender` connection handle for actors and harden the `Error` type.
- src/lib.rs: add `ActorRequestSender<A>` wrapping `mpsc::Sender<ActorRequest<A>>` with async `send`, `Clone`, and `From` impls; expose it via new `Handle::get_connection()` so callers hold a lightweight standalone connection to an actor
- src/lib.rs: route `Handle::send` through the new sender and store `tx` as an `ActorRequestSender`; drop the `Unpin` supertrait bound from the `Actor` trait
- src/error.rs: turn the `Error` type alias into a newtype struct, gate `convert_err` as `pub(crate)`, and add `From<T: AsRef<str>>` plus `ToString` impls
- examples/hello.rs: switch `Greeter::spawn` to method-call syntax (`Greeter.spawn(&rt)`) to match the updated API
- README.md: rename the project heading from "about" to "swactor"
