Add a cargo-fuzz harness exercising the runtime under arbitrary actor spawn/send/inbox sequences in both single- and multi-threaded modes.
- fuzz/Cargo.toml: add an isolated `swactor-fuzz` package (own standalone workspace) wiring libfuzzer-sys + arbitrary against the `swactor` crate, with `fuzz_runtime` and `fuzz_mt` bin targets
- fuzz/fuzz_targets/fuzz_runtime.rs: single-threaded model target running randomized scenarios over Echo/Counter/Forwarder/Spawner/Bomber/Noop/WrongType actors with shared-inbox draining and invariant checks
- fuzz/fuzz_targets/fuzz_mt.rs: multi-threaded target driving a live `Runtime`/`RuntimeHandle` across 2-4 threads with spawn/send/burst/inbox actions and `check_invariants` (worker/actor counts) after each run
- fuzz/fuzz_targets: both targets derive a `FuzzInput`/`Action` model from `arbitrary`, cap the action count, and support opt-in run tracing via the `FUZZ_LOG` env var
- .gitignore: ignore fuzz corpus and artifact output

Split the monolithic crate into a Cargo workspace with the Python and Wasm bindings as separate member crates.
- Cargo.toml: declare a `[workspace]` with members `.`/`crates/swactor-python`/`crates/swactor-wasm`, remove the `python` feature and pyo3 dependency, and change root crate-type from `["cdylib","rlib"]` to `["rlib"]`
- crates/swactor-python: new cdylib crate re-exporting the PyO3 bindings (Runtime/RuntimeConfig/RuntimeHandle/Inbox/Ctx/ActorAddress/RuntimeStats), depending on `swactor` + pyo3; pyproject.toml and uv.lock relocated here from the root
- crates/swactor-wasm: new cdylib crate moved from top-level `wasm/`, depending on `swactor` with `no_random` features
- src/actor.rs: widen `Actor::new`, `AnyActor`, `ContextInner`, and `Ctx::raw_inner` to `pub` so the separate binding crates can drive the runtime
- src/lib.rs: delete the in-tree `python` module and `#[pymodule]`, and gate the `no_random` RNG behind `all(feature = "no_random", not(feature = "getrandom"))`
- tools/: relocate package.json/package-lock.json; drop the now-duplicate `wasm/Cargo.lock`

Refactoring to logically separate component modules in order to make it easier to develop tests, metrics, tracing, etc.

Skeletal actor framework. Somewhat unweildy, needs a message box, a better runtime, and different channels. However, hello world example works
