Claude a7ca6646d7 docs(bench,test): READMEs for benches/ and tests/ 
benches/README.md: catalog of the two bench families (cross-runtime
comparisons + the v0.5 run-queue shootout), how to run the shootout
(scripts/bench_rq.sh, SMARM_BENCH_* knobs, the --no-default-features dance,
summary.csv/RQCSV format), honest-numbers caveats (core count is the
experiment; striped losing at low thread counts is expected), and the
conventions for adding a bench.

tests/README.md: catalog grouped by layer (low-level units / feature areas /
regression+stress), the run matrix (debug-first — that's where the invariant
asserts live — three queue variants, release, loom, trace), why loom tests
live in src/ rather than tests/, and the house conventions: one runtime per
test, oversubscription on purpose, regression tests validated against the
reintroduced bug, odds-stacking for stochastic tests, ordering-not-duration
time assertions, and new-invariant = assert + loom model.

Also fixes a stale header in tests/mutex.rs that claimed 'loom::Mutex' —
it tests smarm::Mutex, and the old name is actively confusing now that loom
is real in this repo.

Claude 978678a46e feat: full runtime redesign (v0.6) 
Complete rewrite with improved architecture & correctness:
- src/runtime.rs: Simplified task scheduling with proper state transitions
- src/scheduler.rs: Decoupled from runtime, pure task queue logic
- src/io.rs, src/mutex.rs: Refactored for clarity & performance
- New actor model framework (src/actor.rs, src/context.rs)
- Channel primitives (src/channel.rs) & process IDs (src/pid.rs)
- Preemption framework (src/preempt.rs) for fair timeslicing
- Expanded benchmarks & tests (multi_scheduler, primes, runtime)

Claude e9fdbb1160 refactor: centralize runtime logic (v0.4) 
Extract scheduler responsibilities into a dedicated Runtime component:
- src/runtime.rs: New centralized control flow (669 lines)
- src/scheduler.rs: Simplified to task queue & preemption management
- tests/runtime.rs: Comprehensive runtime test suite
- benches/multi_scheduler.rs: Multi-runtime scheduling benchmarks
- Improves modularity and enables per-runtime configuration

Claude 8cbef1dfc1 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
