Tom Boucher 1868947088 perf(#316 ): hoist state-lock sleep buffer out of retry loop (#399 )

acquireStateLock was allocating a fresh SharedArrayBuffer on every retry
iteration via Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), ...).
The buffer is never mutated and never escapes, so hoisting it before the loop
is a provably-equivalent transformation — Atomics.wait always sees value 0
whether the buffer is fresh or reused.

Fixes #316

Fixed	316

acquireStateLock no longer allocates a fresh SharedArrayBuffer on every retry iteration — the sleep buffer is now hoisted before the retry loop and reused, eliminating per-retry heap pressure. (#316)
