Despite the `http.Agent` stating:
> The default `http.globalAgent` that is used by `http.request()` has
> all of these values set to their respective defaults.
this isn't true anymore since node.js 19. Both, the http as well as the
https `globalAgent` now set `{ keepAlive: true, scheduling: 'lifo',
timeout: 5000 }` as options. `'lifo'` is the default anyway, but
`keepAlive` is turned off and no `timeout` is set on `new Agent()`.
Document the diverging behaviour in the `globalAgent` sections, remove
the false statement from `http.Agent` section, and extend the changelog
to call out the timeout change as well.

This commit updates the test runner to suppress any output for
filtered tests. Filtered tests no longer generate reporter events,
and the unfiltered tests are renumbered in the output as though
the filtered tests were not present. Skipped tests that are not
filtered are still included in the output.
This change is particularly useful when filtering a large number
of tests, as the previously displayed skip output could be
distracting.

Notable changes:
Added support for import attributes:
Support has been added for import attributes, to replace the old import
assertions syntax. This will aid migration by making the new syntax
available across all currently supported Node.js release lines.

Doc deprecation for `dirent.path`:
Please use newly added `dirent.parentPath` instead.
Experimental node-api feature flags
Introduces an experimental feature to segregate finalizers that affect GC state.
A new type called `node_api_nogc_env` has been introduced as the const version
of `napi_env` and `node_api_nogc_finalize` as a variant of `napi_finalize` that
accepts a `node_api_nogc_env` as its first argument.
This feature can be turned off by defining
`NODE_API_EXPERIMENTAL_NOGC_ENV_OPT_OUT`.

vm: fix V8 compilation cache support for vm.Script:
Previously repeated compilation of the same source code using `vm.Script`
stopped hitting the V8 compilation cache after v16.x when support for
`importModuleDynamically` was added to `vm.Script`, resulting in a performance
regression that blocked users (in particular Jest users) from upgrading from
v16.x.
The recent fixes allow the compilation cache to be hit again
for `vm.Script` when `--experimental-vm-modules` is not used even in the
presence of the `importModuleDynamically` option, so that users affected by the
performance regression can now upgrade. Ongoing work is also being done to
enable compilation cache support for `vm.CompileFunction`.

This patch adds `require()` support for synchronous ESM graphs under
the flag `--experimental-require-module`
This is based on the the following design aspect of ESM:
- The resolution can be synchronous (up to the host)
- The evaluation of a synchronous graph (without top-level await) is
also synchronous, and, by the time the module graph is instantiated
(before evaluation starts), this is is already known.
If `--experimental-require-module` is enabled, and the ECMAScript
module being loaded by `require()` meets the following requirements:
- Explicitly marked as an ES module with a `"type": "module"` field in
the closest package.json or a `.mjs` extension.
- Fully synchronous (contains no top-level `await`).
`require()` will load the requested module as an ES Module, and return
the module name space object. In this case it is similar to dynamic
`import()` but is run synchronously and returns the name space object
directly.
```mjs
// point.mjs
export function distance(a, b) {
return (b.x - a.x) ** 2 + (b.y - a.y) ** 2;
}
class Point {
constructor(x, y) { this.x = x; this.y = y; }
}
export default Point;
```
```cjs
const required = require('./point.mjs');
// [Module: null prototype] {
// default: [class Point],
// distance: [Function: distance]
// }
console.log(required);
(async () => {
const imported = await import('./point.mjs');
console.log(imported === required); // true
})();
```
If the module being `require()`'d contains top-level `await`, or the
module graph it `import`s contains top-level `await`,
[`ERR_REQUIRE_ASYNC_MODULE`][] will be thrown. In this case, users
should load the asynchronous module using `import()`.
If `--experimental-print-required-tla` is enabled, instead of throwing
`ERR_REQUIRE_ASYNC_MODULE` before evaluation, Node.js will evaluate the
module, try to locate the top-level awaits, and print their location to
help users fix them.

When the entry point is a module and the graph it imports still
contains unsettled top-level await when the Node.js instance
finishes the event loop, search from the entry point module
for unsettled top-level await and print their location.
To avoid unnecessary overhead, we register a promise that only
gets settled when the entry point graph evaluation returns
from await, and only search the module graph if it's still
unsettled by the time the instance is exiting.
This patch only handles this for entry point modules. Other kinds of
modules are more complicated so will be left for the future.
Drive-by: update the terminology "unfinished promise" to the
more correct one "unsettled promise" in the codebase.

- As far as I can tell, the documentation didn't say this, so I was left
wondering if there is a difference between `c1` and `c2` in `const c2
= vm.createContext(c1);` According to my own tests, they are equivalent.
I thought it was worth documenting as it would've saved me a bit of time
if this information were written down.

This is similar to the `queryObjects()` console API provided by the
Chromium DevTools console. It can be used to search for objects that
have the matching constructor on its prototype chain in the entire
heap, which can be useful for memory leak regression tests. To avoid
surprising results, users should avoid using this API on constructors
whose implementation they don't control, or on constructors that can
be invoked by other parties in the application.
To avoid accidental leaks, this API does not return raw references to
the objects found. By default, it returns the count of the objects
found. If `options.format` is `'summary'`, it returns an array
containing brief string representations for each object. The visibility
provided in this API is similar to what the heap snapshot provides,
while users can save the cost of serialization and parsing and directly
filer the target objects during the search.
We have been using this API internally for the test suite, which
has been more stable than any other leak regression testing
strategies in the CI. With a public implementation we can now
use the public API instead.
