Adds the std crate on top of the core runtime: Supervisor with RestartPolicy
(Permanent/Transient/Temporary) and SupervisorStrategy (OneForOne/OneForAll/
RestForOne), Router with RoutingStrategy, name/monitor/group registries, StdExtension,
and Ctx/Runtime extension traits. Also extends core (worker, actor, delivery identity
hashing, config, stats), adds a fuzz target, a proptest suite, expands runtime_api
tests, and adds cfuzz cycle notes + benchmarks.

Make mailbox push infallible and replace the locked tick-timing buffer with a
lock-free ring.
- channel: HybridChannel::push and Sender::send now return () — overflow always
absorbs, never rejects — dropping the Result<(), T> surface and its callers.
- stats: tick_timings moves from Mutex<VecDeque> to a lock-free crossbeam
ArrayQueue (drop-oldest-on-full), removing the per-tick lock.
- ripple the signature change through worker/runtime/config; drop worker_benchmarks.
- expand runtime_api tests around the new channel/stats shapes.
