Fix nonblocking FFI to retain ArrayBuffer backing stores (
764ce2f)
Nonblocking FFI calls now keep BackingStore references alive until the background thread finishes, preventing V8 GC from freeing ArrayBuffer memory early and leaving dangling pointers. This closes a real use-after-free hazard in async FFI paths involving buffer, struct, and out-buffer arguments.
Add OTEL array-valued attributes (f0e7923)
Telemetry attributes can now carry homogeneous arrays of strings, numbers, booleans, and bigints instead of dropping them. That makes OpenTelemetry export more complete for apps that attach list-valued metadata to spans.
Speed up V8-to-Rust string conversion (4a19007)
Deno core now uses newer rusty_v8 APIs and a reusable thread-local buffer to cut down string conversion overhead, reducing FFI calls on hot paths. This is a performance-focused runtime improvement that should benefit ops and helpers that move lots of strings across the V8/Rust boundary.
Reuse the threadpool for async N-API work (216126e)
Async N-API work now goes through spawn_blocking instead of spawning a fresh OS thread per task. That lowers scheduling and creation overhead, especially on Linux, and brings the behavior closer to Node's worker-pool model.
Tighten Node compat around networking and child_process (954edda, 
f7a43a2, 262cb59, 60edd78)
Node polyfills picked up several behavior fixes: udp.send() now requires net permission, invalid child_process.send(..., handle) values raise the proper handle-type error, and JSON IPC messages regain normal Object.prototype semantics. Deep-equality comparisons were also corrected for invalid dates, promises, maps/sets, and a few loose-equality edge cases to match Node's test suite more closely.
