Node.js 19.0.0 Released

This release changes default behavior and removes some tooling support.

• Outgoing HTTP(s) connections now default to keepAlive: true with a 5 second waiting window, changing connection reuse behavior
• Node.js HTTP servers now automatically disconnect idle keep-alive clients when close() is invoked
• DTrace, SystemTap, and ETW support has been removed entirely
• exports double slash maps now trigger a runtime deprecation warning
• Coercion to integer in process.exit() now triggers a runtime deprecation warning
• Minimum ICU version bumped to 71, which may affect builds depending on bundled ICU
• webcrypto.Crypto.prototype.CryptoKey (non-standard) has been removed
• crypto.setFips can no longer be called from a worker thread

Move to Node.js 19.0.0 to pick up these changes, testing HTTP client/server behavior given the new keep-alive default.

• Remove any reliance on DTrace, SystemTap, or ETW tracing for Node.js processes
• Update code using exports double slash maps to avoid the deprecation warning
• Replace any integer coercion patterns passed to process.exit() with explicit integer values
• Check for usage of webcrypto.Crypto.prototype.CryptoKey and update accordingly
• Verify crypto.setFips calls are not made from worker threads
• Confirm build environments meet the ICU 71 minimum if using system ICU
