Highlights

Native NestJS support — express adapter, DI container, decorators + reflect-metadata, rxjs interceptor interop, guards/pipes/filters (#5739, #5758–#5760, #5721)
New current-thread async runtime — JS-loop-driven runtime with wait-driver and gated fast-native-drive; native I/O and JS interleave on one thread, Node's model, eliminating the cross-thread lost-wakeup family (#5831, supersedes #5779). A link-order bug that could strand the new runtime (test-only perry_ffi shims shadowing the real bridge) was found and fixed in the same release (#5892, #5911)
CPS async lowering for async class methods, capturing-closure functions, and nested async closures (#5854)
Representation-aware type lowering with a native-ABI material-evidence gate in CI (#5466)
Embed static assets into standalone executables (#5754) and eval-mode worker_threads Workers from inline source (#5799)
Promise spec-compliance batch — then/finally SpeciesConstructor + error propagation (#5767), user-defined own then honored (#5748), own-property dispatch fixes (#5865), reaction-slot clobber fix for the webpack/Turbopack shared-chunk-promise hang (#5867)

Large conformance waves across Object, String, JSON, Function, Promise, Proxy, WeakMap/WeakSet, RegExp, Temporal, Intl, annexB, and eval/global-scope semantics (#5579–#5592 clusters, #5824, #5842–#5849, #5876–#5883)
