Add i32 remainder tests for negative dividends across non-power-of-two moduli (#4665)

The existing remainder cases only use moduli 10 and 256 (from the sparse i32 range), missing value-dependent codegen paths such as modulus 768 where some implementations compute signed % as unsigned for negative operands (e.g. -1 % 768 returns 255 instead of -1). Add a remainder_negative test covering negative dividends across moduli 3/7/100/256/768/1000. See https://github.com/gfx-rs/wgpu/issues/8191.

Access subgroupMinSize/subgroupMaxSize directly on GPUAdapterInfo (#4663)

These properties are now exposed on GPUAdapterInfo, so the local
SubgroupProperties interface and the adapterInfo as SubgroupProperties
casts are no longer needed. Read them directly via
adapterInfo.subgroupMinSize / adapterInfo.subgroupMaxSize.

They are still declared optional in @webgpu/types (number | undefined),
so a non-null assertion (!) is used at these call sites, which are all
gated on the subgroups (or subgroup-size-control) feature where the
values are guaranteed to be present.

Add shared support for WGSL immediate validation (#4658)

• Add shared support for WGSL immediate validation

This patch adds the shared CTS plumbing needed by the follow-up
WGSL immediate address space validation tests.

It adds immediate_address_space to the known WGSL language feature
list, models immediate in the address space metadata, and treats it
as a module-scope, unbound, read-only address space with
host-shareable store types.

The validation helpers emit the required WGSL requires directive and
skip immediate tests when immediate data is not exposed by the browser.
The skip checks setImmediates/maxImmediateSize because current
Chrome Canary exposes the API before advertising the WGSL feature.

This also removes two now-unnecessary address-space type assertions
that became redundant once the shared metadata was typed by
AddressSpace.

• Apply suggestions from code review

Will remove them when real immediate case added.

Skip quadBroadcast/quadSwap split tests when subgroup size < 8 (#4656)

When the implementation selects a subgroup size < 8 for the test's
workgroup, the split predicate id < subgroupSize / 2 bisects the
only quad in the subgroup, leaving no fully active quad — which is
undefined behavior for quad operations. This is observed on WARP
(which selects its native D3D12 wave size: 4 on arm64 NEON, often 4
on x86 for small workgroups) and may occur on any implementation
that picks a small native subgroup size at runtime.

Two coordinated guards:

• In the shader, the quad call is wrapped in
  if subgroupSize >= 8u { ... } so it never executes when the
  split predicate would be unsafe.
• In the JS checker, the actual subgroupSize is read out of
  metadata.subgroup_size[0] and the test is skipped with t.skip
  when it is < 8, so the missing output doesn't get flagged as a
  failure.

Querying GPUAdapterInfo.subgroupMinSize would not be sufficient: the
size the implementation actually selects depends on the shader (its
workgroup size, register pressure, etc.), not just the adapter's
minimum supported size. Reading subgroupSize from inside the test
shader itself is the only reliable signal.

Add shader validation tests on subgroup-size-control - Part II (#4648)

• Add shader validation tests on subgroup-size-control - Part II

This patch adds the second part of the shader validation tests on the
extension subgroup-size-control:

• The value of @subgroup_size must be a constant expression or an
  override expression that resolves to an i32 or an u32.
• The value of @subgroup_size must be a power of 2.
• The x-dimension of the entry point's workgroup_size must be a
  multiple of the @subgroup_size value, or a pipeline creation error
  occurs

Issue: #4640

These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor dom/webgpu/tests/cts/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.
