Node compat and fetch reliability land

Deno adds a developer CLI and ships several Node compatibility fixes, plus stale HTTP retry and FreeBSD signal handling.

Node compatibility gets a batch of fixes

Several Node polyfills were tightened up in ways that unblock real packages and tests: child_process.kill(0) now works as a process-liveness check, node:dgram compatibility improved, generateKeyPair(type, callback) handles the 2-arg form, and TLS cleanup no longer leaks a JS stream socket resource that could hang the event loop. These are the kind of fixes that directly reduce breakage for npm and Node-compat workloads. (bartlomieju7bcaaa2, bartlomieju130a377, bartlomiejue55b986, fraidev26972e6)

Fetch now retries stale pooled connections

fetch() was taught to retry when a pooled HTTP/1.1 connection has gone stale and the server has already restarted or closed the socket. That closes a user-visible reliability gap where every other request could fail with connection closed before message completed. (bartlomiejue0464f4)

Upgrade rejection with non-101 responses now works

node:http upgrade handling can now reject an upgrade request with a normal non-101 response instead of throwing a parser/write error. This makes it possible to return responses like 401 during upgrade negotiation and keep the server alive for later requests. (littledivybd3fd9a)

FreeBSD signal registration no longer panics

Deno fixed a FreeBSD-specific signal-table bug that could panic when registering signals because SIGLIBRT was incorrectly included even though it does not exist there. The change also surfaces registration failures as I/O errors instead of unwrapping. (amyssnippet7c84b09)

npm bin setup handles read-only executables

The npm installer now copes with package bin files that are executable but not writable, avoiding EACCES during .bin setup. This matches how some tarballs are published in the wild and prevents install-time failures. (bartlomiejucbdfed1)

Developer CLI lands at ./x

A new top-level ./x script adds a convenience CLI for common contributor workflows like build, check, test, and lint tasks. It centralizes internal repo commands and should make day-to-day development faster. (1190dc9)
