Matteo Collina's twelfth round of pure-JS webstreams optimization cuts promise overhead by redesigning microtask handling on hot paths, while Node adds DatabaseSync diagnostic channels for production visibility.

The webstreams optimization [1] rewires three critical paths to eliminate unnecessary promise allocations per chunk. Instead of coercing every callback result into a promise, the runtime now fast-paths synchronous returns through a shared resolved promise, skipping the observable then() lookup. Profiling showed roughly 10% of pipeTo's cycles burned in queueMicrotask and its native binding alone, a problem this commit surgically addresses by reducing per-backpressure-flip promise reactions. SQLite support continues maturing with DatabaseSync diagnostic channels [2] landing for production observability, letting applications hook into query execution without performance degradation. Documentation fixes follow: constructor type signatures in the API docs now correctly infer instance returns instead of void [3], and accessibility issues in the ChangeHistory component are resolved [4]. The QUIC implementation also received a critical wake-up fix [5] that corrects the assumption that setWakeUp executes once per event loop cycle, replacing it with setImmediate guarantees.

Action items

→ Review webstreams optimization for downstream impacts on custom sink/source implementations nodejs/node [plan]
→ Enable DatabaseSync diagnostics in production monitoring if running SQLite workloads nodejs/node [monitor]
→ Check QUIC deployments against issue #64035 if using high-frequency wake-up patterns nodejs/node [plan]
