SudhansuBandha 746624951f watch: track worker entry files in watch mode 
Currently, --watch mode only tracks dependencies from the main
module graph (require/import). Worker thread entry points created
via new Worker() are not included, so changes to worker files do
not trigger restarts.

This change hooks into Worker initialization and registers the
worker entry file with watch mode, ensuring restarts when worker
files change.

 		b92c9b5ff5 worker: eliminate race condition in process.cwd() 
Fixes a race condition in worker thread cwd caching where the counter
is incremented before the directory change completes, allowing workers
to cache stale directory values.

In lib/internal/worker.js, the main thread's process.chdir() wrapper
previously incremented the shared counter before calling the actual
chdir(), creating a race window where workers could read the old
directory but cache it with the new counter value. This caused
subsequent cwd() calls to return incorrect paths until the next chdir().

This fix reorders the operations to change the directory first, then
increment the counter, ensuring workers are only notified after the
directory change completes.

Before fix: 54.28% error rate (311/573 races)
After fix: 0% error rate (0/832 races)

It is similar to `workerData` except that environment data is set

passed automatically to all new Workers.

This is a *partial* fix of https://github.com/nodejs/node/issues/30992

Anna Henningsen 5968c54235 worker: fix interaction of terminate() with messaging port 
When a Worker is terminated, its own handle and the public
`MessagePort` are `.ref()`’ed, so that all relevant events,
including the `'exit'` events, end up being received.

However, this is problematic if messages end up being queued
from the Worker between the beginning of the `.terminate()` call
and its completion, and there are no `'message'` event handlers
present at that time. In that situation, currently the messages
would not end up being processed, and since the MessagePort
is still `.ref()`’ed, it would keep the event loop alive
indefinitely.

To fix this:

- Make sure that all messages end up being received by
  `drainMessagePort()`, including cases in which the port had
  been stopped (i.e. there are no `'message'` listeners) and
  cases in which we exceed the limit for messages being processed
  in one batch.
- Unref the Worker’s internal ports manually after the Worker
  has exited.

Either of these solutions should be solving this on its own,
but I think it makes sense to make sure that both of them
happen during cleanup.

Trevor Norris 04d16646a0 worker: add eventLoopUtilization() 
Allow calling eventLoopUtilization() directly on a worker thread:

    const worker = new Worker('./foo.js');
    const elu = worker.performance.eventLoopUtilization();
    setTimeout(() => {
      worker.performance.eventLoopUtilization(elu);
    }, 10);

Add a new performance object on the Worker instance that will hopefully
one day hold all the other performance metrics, such as nodeTiming.

Include benchmarks and tests.
