Returns a structured list of all interactive elements on a page:
buttons, links, inputs, ARIA widgets, contenteditable regions, and
elements with event listeners. Includes accessible names, roles,
listener types, and key attributes.
Event listener introspection (both addEventListener and inline
handlers) is unique to LP — no other browser exposes this to
automation code.
Instead of always returning zeros, delegate getBoundingClientRect and
getClientRects to the common ancestor container element. Return zeros
only when the range is collapsed or has no element ancestor.
When a module's compilation fails after its imported_modules entry has
been consumed by waitForImport, sibling modules that import the same
dependency would get UnknownModule errors. Fix by re-preloading modules
whose cache entry exists but has no compiled module.
A inner-navigate event can override an existing pending queued navigation. When
it does, the previously queued navigation has to be cleaned up. We were doing
this, but it must have been stripped out when navigation was refactored to work
with frames.
headless stubs returning zero-valued DOMRect / empty list per CSSOM
View spec. fixes "getBoundingClientRect is not a function" errors on
sites where layout code calls this on Range objects (e.g. airbnb).
headless stub for the FontFace API — constructor stores family/source,
status is always "loaded", load() resolves immediately. enables sites
that use new FontFace() for programmatic font loading (e.g. boursorama).
Scripts created via createElement('script') with inline content (textContent,
text, or innerHTML) and inserted into the DOM now execute per the HTML spec.
Previously all dynamically inserted scripts without a src attribute were
skipped, breaking most JS framework hydration patterns.
atob, Performance.measure, and Navigation methods (back, forward,
navigate, traverseTo, updateCurrentEntry) return DOMException errors
but were missing the dom_exception flag, causing them to throw generic
Error objects instead of proper DOMException instances in JavaScript.

It isn't safe/correct to call `navigate` on the same page multiple times. A page
is meant to have 1 navigate call. The caller should either remove the page
and create a new one, or call Session.replacePage.
This commit removes the *Page from the MCP Server and instead interacts with
the session to create or remove+create the page as needed, and lets the Session
own the *Page.
It also adds a bit of defensiveness around parameter parsing, e.g. calling
{"method": "tools/call"} (without an id) now errors instead of crashing.
This is a follow up to ca0f77bdee that applies
the same fix to all places where cloneNode is used and then the cloned element
is inserted. A helper was added more of a means of documentation than to DRY
up the code.

Instead of going through the parser, just create / append the 3 elements.
iframe without a src automatically loads about:blank. This is important, because
the following is valid:
```js
const iframe = document.createElement('iframe');
document.documentElement.appendChild(iframe);
// documentElement should exist and should be the HTML of the blank page.
iframe.contentDocument.documentElement.appendChild(...);
```
