feat: I/O and mutex support (v0.3)

Add epoll-based non-blocking I/O and kernel-like mutexes:
- src/io.rs: Complete epoll backend with timeout & error handling
- src/mutex.rs: Fair mutex with waiter queues & parking integration
- Enhanced scheduler to support synchronous I/O blocking
- Comprehensive test suites for I/O (epoll) and mutex behavior
- Documentation: LOOM.md concurrency model & README

timer: sleep(duration) via min-heap of (deadline, pid)

Adds a BinaryHeap of timer entries on SchedulerState. sleep() inserts
an entry and parks; schedule_loop pops due entries each iteration and
unparks them. When the run queue is empty but timers are pending, the
OS thread sleeps until the soonest deadline.

Single-threaded only; thread::sleep is fine because no other thread
can wake us. The IO thread coming next will need a Condvar or pipe
wakeup to break this OS-sleep early.

v0.1: green-thread actors, supervision, channels, benchmark

Hand-rolled context switching on mmap'd stacks with guard pages,
allocator-driven RDTSC preemption, unbounded MPSC channels, supervision
via per-slot Signal mailboxes, root supervisor as sentinel PID.

Lib + tests + benches clean check/clippy. All 29 tests pass.
Bench: smarm 3.4% over serial baseline, within 160us of tokio
current-thread on prime-counting fan-out.
