layout: Enable using cached fragments when there is a BoxTree update point (#36404)
This starts to enable the fragment cache for all layout modes, except
grid. The main tricky bit here is that update points are absolutes and
these need to be laid out again in their containing blocks. We punt a
little bit on this, by forcing ancestors of update points to rebuild
their Fragments. This is just the first step.

Testing: We do not currently have layout performance tests, but will try
to run some tests manually later. Behavior is covered by the WPT.

Add serde and wgsl features to wgpu-core (#36411)
This fixes errors when running `./mach clippy -r -p layout_2020` and
`./mach clippy -r -p script`.

Also addressing an unused import warning when running the latter.

Testing: These changes do not require tests because it's just a compile

script: copy include! files from script_bindings to script's OUT_DIR (#36384)
copy generated `include!`d files from script_bindings's OUT_DIR, to
script's OUT_DIR to allow Rust Analyzer to load them.
This is done to bypass limitation of Rust Analyzer:
https://github.com/rust-lang/rust-analyzer/issues/17040

Also build script will now be rerun only when there are actual changes
to concrete bindings due to emitted `cargo::rerun-if-changed` (not for
each change in script crate).

Testing: It compiles so it works, I tested manually and RA now works as
expected (although we need to from type alias to concrete union-types
definitions)

Devtools: initial Debugger > Sources panel (#36164)
This patch adds support for listing scripts in the Sources panel.
Classic scripts, both external and inline, are implemented, but worker
scripts and imported module scripts are not yet implemented.

For example:

```html
<!-- sources.html -->
<!doctype html><meta charset=utf-8>
<script src="classic.js"></script>
<script>
    console.log("inline classic");
    new Worker("worker.js");
</script>
<script type="module">
    import module from "./module.js";
    console.log("inline module");
</script>
<script src="https://servo.org/js/load-table.js"></script>
```

```js
// classic.js
console.log("external classic");
```

```js
// worker.js
console.log("external classic worker");
```

```js
// module.js
export default 1;
console.log("external module");
```

Fix radio group validity update when removing or selecting an input (#36252)
This PR fixes an issue where radio inputs in the same group failed to
correctly update their `validity.valueMissing` state when:

- A **checked radio button was removed** from the DOM.
- A **different radio button was selected** by user interaction.

This behavior caused mismatches with how browsers like Firefox handle
radio group validation.

---

### Changes in This PR

#### Radio group revalidation on DOM removal
- Updated `unbind_from_tree()` to revalidate other radio buttons in the
same group when a checked input is removed.
- Uses `UnbindContext::parent` as the DOM root to ensure the correct
context is used during traversal.

#### New helper: `find_related_radios()`
- Encapsulates logic for finding other inputs in the same group.
- Used during both removal and attribute changes for consistency.

#### Validation on `checked`/`value` updates
- Introduced `update_related_validity_states()` to revalidate all group
members when a radio's `checked` or `value` is changed.

#### Web Platform Test (WPT) coverage
- Created a new WPT file: `radio-group-valueMissing.html`.
- Tests follow recommended `test()` pattern:
  - **Precondition**: Assert initial `valueMissing`.
  - **Action**: Remove or select a radio.
  - **Postcondition**: Assert expected `valueMissing`.

#### Manifest updated
- The WPT manifest now includes the new test.

compositing: Combine webrender_traits and compositing_traits (#36372)

but now that the compositor doesn't depend directly on `script` any
longer and the `script_traits` crate has been split into the

Move ScriptToConstellationMsg to constellation_traits (#36364)
This is the last big change necessary to create the
`constellation_traits` crate. This moves the data structure for messages
that originate from the `ScriptThread` and are sent to the
`Contellation` to `constellation_traits`, effectively splitting
`script_traits` in half. Before, `script_traits` was responsible for
exposing the API of both the `ScriptThread` and the `Constellation` to
the rest of Servo.

- Data structures that are used by `ScriptToConstellationMsg` are moved
  to `constellation_traits`. The dependency graph looks a bit like this:
  `script_layout_interface` depends on `script_traits` depends on
  `constellation_traits` depends on `embedder_traits`.
- Data structures that are used in the embedding layer
  (`UntrustedNodeAddress`, `CompositorHitTestResult`, `TouchEventResult`
  and `AnimationState`) are moved to embedder_traits, to avoid a
  dependency cycle between `webrender_traits` and
  `constellation_traits`.
- Types dealing with MessagePorts and serialization are moved to
  `constellation_traits::message_port`.

Testing: This is covered by existing tests as it just moves types
around.

Make the memory reporting multi-process aware (#35863)
So far the memory reporter aggregates reports from all processes, and
runs the system reporter only in the main process. Instead it is
desirable to have per-process reports. We do so by:
- creating a ProcessReports struct that holds includes the pid in
addition to the reports themselves.
- running the system memory reporter also in content processes.
- updating the about:memory page to create one report per process, and
add useful information like the pid and the urls loaded in a given
process.

constellation: Only return focused browsing contexts that exist. (#36330)
The webdriver server relies on the constellation to report which
browsing context is focused, and assumes that a focused context is ready
for interaction. However, new browsing contexts exist in a weird state
where they are not tracked by the constellation until the initial load
is complete, which leads to the constellation rejecting attempts to
navigate a browsing context right after it's created. These changes
ensure the constellation does not report a browsing context as focused
until it's actually created and ready for interaction.

constellation: Rename messages sent to the Constellation (#36341)
Messages that are sent to the `Constellation` have pretty ambiguous
names.
This change does two renames:

- `ConstellationMsg` → `EmbedderToConstellationMessage`
- `ScriptMsg` → `ScriptToConstellationMessage`

This naming reflects that the `Constellation` stands in between the
embedding layer and the script layer and can receive messages from both.
Soon both of these message types will live in `constellation_traits`,
reflecting the idea that the `_traits` variant for a crate is
responsible for exposing the API for that crate.

Testing: No new tests are necessary here as this just renames two enums.

Prevent zombie processes in multi-process mode. (#36329)
This introduces a process manager that holds for each process a
"lifeline": this is the receiving end of a ipc channel that is not used
to send anything, but only to monitor the process presence. We turn that
ipc receiver into a crossbeam one to integrate the monitoring into the
constellation run loop. The sender side is made part of the initial
"UnprivilegedContent" data structure sent to the new process, both for
content and for service worker processes.

script: Remove code dealing with CompositorUntrustedNode (#36343)
There used to be two kinds of untrusted nodes, but these have been
unified, so the duplicate methods dealing with them in `script` can be
removed.

Testing: This is covered by existing tests as it shouldn't change
any behavior.

constellation: Stop assuming that the viewport is shared by all WebViews (#36312)
The `Constellation` previously held a `window_size` member, but this
assumes that all `WebView`s have the same size. This change removes that
assumption as well as making sure that all `WebView`s pass their size
and HiDIP scaling to the `Constellation` when they are created.

In addition

- `WindowSizeData` is renamed to `ViewportDetails`, as it was
holding more than just the size and it didn't necessarily correspond to
  a "window." It's used for tracking viewport data, whether for an
  `<iframe>` or the main `WebView` viewport.
- `ViewportDetails` is stored more consistently so that conceptually an
  `<iframe>` can also have its own HiDPI scaling. This isn't something
  we necessarily want, but it makes everything conceptually simpler.

The goal with this change is to work toward allowing per-`WebView` HiDPI
scaling and sizing. There are still some corresponding changes in the
compositor to make that happen, but they will in a subsequent change.

Testing: This is covered by existing tests. There should be no behavior
changes.
Fixes: This is part of #36232.

script: Remove dependency on webgpu (#36332)
After #36320, `script` only depends on `webgpu` for its type aliases to
`wgpu_core` and `wgpu_types`. This change removes the dependency on
`webgpu` in favor of depending directly on the upstream crates. This
makes it so that you can change `webgpu` without recompiling `script`.

Testing: This change is covered by existing WebGPU tests and is mainly
just changing the way dependencies are accessed.

layout: Restrict stretch alignment to flex items with computed auto size (#36288)
We were allowing `align-self: stretch` to stretch flex items whose cross
size behaves as `auto`, including cyclic percentages.

However, https://github.com/w3c/csswg-drafts/issues/4525 resolved that
stretching should only happen when the cross size computes to `auto`.

So this patch exposes this information in `ContentBoxSizesAndPBM`, and
refactors the flexbox stretching logic.

Fixes: #36285

webgpu: Add a webgpu_traits crate (#36320)
This breaks the `script_traits` dependency  on `webgpu`. In general, the
`traits` crates shouldn't depend on Servo non-`traits` crates. This is
necessary to move "script to constellation" messages to the
`constellation_traits` crate, making it the entire API for talking to
the
constellation. This will break a circular dependency when that happens.

Testing: Successfully building is enough of a test for this one as
it is mainly moving types around.

Move generated bindings to script_bindings (#36323)
This is the final step of #1799, where the majority of the generated
code for the JS bindings is now compiled as part of the script_bindings
build step. The remaining pieces in script must live there because they
refer to concrete DOM types; all code in script_bindings is generic over
the
[DomTypes](https://doc.servo.org/script/dom/bindings/codegen/DomTypes/trait.DomTypes.html)
trait.

My testing with incremental builds shows me a 12 second reduction in
build times on my 2024 M4 Macbook Pro when modifying code in the script
crate after these changes. Before this PR those changes took 20 seconds
to rebuild Servo, and now they take 8 seconds.

Testing: Existing WPT tests ensure no regressions.
Fixes: #1799

Support single-value <select> elements (#35684)
https://github.com/user-attachments/assets/9aba75ff-4190-4a85-89ed-d3f3aa53d3b0



Among other things this adds a new `EmbedderMsg::ShowSelectElementMenu`
to tell the embedder to display a select popup at the given location.

This is a draft because some small style adjustments need to be made:
* the select element should always have the width of the largest option
* the border should be part of the shadow tree

Apart from that, it's mostly ready for review.

<select id="c" name="choice">
