sycl: Add optional USM system allocations (#22526)
This introduces an optional feature to allocate large GPU buffers (≥ 1GB)
using USM system allocations if supported by the device. It allows using
buffers from the system allocator then letting the system manage memory
migrations between host and device as necessary.
This feature is disabled by default and requires the GGML_SYCL_USM_SYSTEM
environment variable to enable. If USM system allocations are not supported
by the device or the system, we fallback to regular allocations.
This feature can allow VRAM overcommit. For example, the test below fails
on B580 due to lack of memory for allocation, but it passes when enabling
USM system allocations:

ui: add source toggle to mermaid and svg blocks (#24652)
* ui: add source toggle to mermaid and svg blocks
Add a toggle button next to copy and preview that switches a rendered
mermaid or svg block to its source code and back. The button is shared by
both block types and the rendered view stays the default.
The source view reuses the code block scroll container and the highlighted
code element captured at transform time, so it matches the app code blocks
without highlighting again.
Make tall diagrams scroll like text code blocks: safe centering keeps the
diagram centered when it fits and falls back to start alignment when it
overflows, so the top stays reachable instead of clipping above.
Keep the block header opaque and layered above the scrolled diagram, and
ignore header clicks in the zoom handler, so a button click never falls
through to the zoom dialog.

Fix and restrict NVFP4 edge-cases in llama-graph (#24331)
* Move post-GEMM MUL required for dequant b4 lora and bias add

1. For lora, I would presume we want fully dequantized values before
doing the residuals, but this depends on how the LORAs were

- Move the svg size ceiling and DOMPurify config out of sanitize-svg.ts into /constants.

Mount each sanitized svg inside an open shadow root so author <style> and
keyframe or smil animations run while staying scoped to the host element.
Relax the sanitizer to forbid only foreignObject and script, which lets
animation, href and external resource refs through for wider compatibility.
Render the inline block and the zoom dialog from the same reactive source,
so a streaming svg keeps drawing live inside the open zoom popup.

UI/jpeg exif orientation (#24196)
* ui: bake jpeg exif orientation into uploaded images
stb_image in mtmd ignores exif metadata, so rotated smartphone photos
reach the model with raw pixel orientation. The webui now reads the
exif orientation tag at send time and feeds it into the existing
capImageDataURLSize canvas pass: the browser applies the rotation when
decoding, so capped images come out upright for free, and images under
the cap threshold get a single plain redraw when orientation > 1.
At most one re-encode ever happens per image. Upright jpegs with
capping disabled pass through untouched, bit perfect.
Adds jpeg-orientation.ts with a minimal exif parser working on a
bounded base64 prefix (both endianness, returns 1 on any malformed
input) and unit tests against handcrafted jpeg byte streams.
* ui: move jpeg exif constants into lib/constants

Covers capImageDataURLSize end to end in chromium with real Pillow
generated jpeg fixtures across exif orientations 1/3/5/6/8: upright
quadrant colors checked pixel-wise, expected dimensions with and
without capping, no orientation tag left in the output, and strict
passthrough when nothing needs rewriting.
