The OS signals tutorial previously only mentioned SIGINT and SIGBREAK on Windows. Updates the leading note and adds a new "Windows support" section listing the full sets supported by addSignalListener and Deno.kill as of Deno 2.8 (SIGTERM, SIGQUIT, SIGKILL, SIGABRT, signal 0). Notes that SIGKILL / SIGABRT cannot be registered as listeners. Refs denoland/deno#32689
SIGTERM/SIGQUIT support on Windows shipped in 2.7.6 (deno#32689), not 2.8.

Deno.addSignalListener(sig, …)omitsSIGHUPandSIGWINCHfrom the Windows listener set. Currentdenoland/denocli/tsc/dts/lib.deno.ns.d.tsdocuments Windows support forSIGINT,SIGBREAK,SIGTERM,SIGQUIT,SIGHUP, andSIGWINCH, andext/signals/dict.rsmaps those signals on Windows; please include both in the warning/table so this page does not under-document supported listeners.last_modified: 2025-03-10is unchanged for this content update. Please bump the frontmatter date for the page update.

examples/tutorials/os_signals.md— Windows now also supportsSIGTERMandSIGQUITforaddSignalListener.Deno.addSignalListener—SIGINT,SIGBREAK,SIGTERM,SIGQUIT.Deno.kill— additionally acceptsSIGKILL,SIGABRT, and signal0for health checks (all map toTerminateProcess).SIGKILL/SIGABRTare deliberately not registerable as listeners (matches Unix).Test plan
deno task serve— tutorial renders, the new section's table aligns.
