* fix(blend): Soft Light uses the W3C curve over dark backdrops (#8804)
Photoshop's Soft Light moves the backdrop towards D(cb) in the upper half,
and D(cb) is the cubic ((16·cb − 12)·cb + 4)·cb below a quarter, not
sqrt(cb). With sqrt the Soft Light cell of psd-tools rgb-blend-modes.psd
was up to 20 levels too light over the dark rainbow; with the cubic it is
within 4 of Photoshop's merged image.
Same change in compose.wgsl so the GPU compositor stays at CPU parity.
Krita's own soft_light (the sqrt curve) now opens as the approximation and
svg:soft-light / krita:soft_light_svg as the exact match, without warning.
Fixes#8804
* compose: the see-through Soft Light test expects the W3C curve over a dark backdrop (#8804)
The #6232 test computed Photoshop's Soft Light of yellow as sqrt(b) for red and
green. Its backdrop #04170F is below a quarter in both channels, where the W3C
curve (Photoshop's, measured in #8804) uses ((16b - 12)b + 4)b instead.
- gpu: the test modules share one GPU_LOCK, and timing and vector_mask
take it too, so one process drives one wgpu device at a time.
- ui-egui: the wgpu tests in pattern_preview_canvas, adjust_preview_gpu,
marquee_autoscroll and layout_perf take gpu_lock().
- affinity compound_limits: the child process selects its test by the
module path (compound_limits::<name>); with --exact, the bare name
matches no test and the child passes without running the check.
- xtask scorecard reads crates/io/tests/it/corpus.rs.
- Docs and comments name the new test paths and the --test it filters.
* OpenRaster: never overwrite an .ora with less than the document has (#3806)
File › Save wrote any document back to its .ora, though OpenRaster
drops adjustment layers, layer styles, vector masks and clipping,
applies masks and fill opacity to the pixels and rasterises type and
shape layers; the save then marked the document saved, so the edits
were lost without asking.
An OpenRaster file now counts as the document's own file only while
it holds everything in it. photocraft_io::ora_losses lists what a save
would leave out, from the same checks the writer warns with but
without encoding anything, and file_cmds::holds says whether a format
keeps the whole document (PSD, PSB and .pcraft always; OpenRaster when
nothing is lost). When it doesn't:
- File › Save opens Save As on a PSD of the same name, with a notice
listing what OpenRaster would drop, instead of overwriting the .ora;
- a save to an .ora path writes a copy, as Photoshop does for formats
that can't keep everything: the document keeps its file and stays
unsaved;
- automation (app.save, the headless doc.save) refuses a pathless save
with the reasons and treats an .ora save as a copy.
An sRGB profile is no longer reported as lost, as OpenRaster readers
assume sRGB. A plain document still saves back to its .ora.

* i18n(vi): translate the OpenRaster save notice
vi.tsv is now a complete catalog, so the two new strings need
Vietnamese rows. Terms follow the catalog's own: Không thể for
can't, như for such as, Lưu bản sao for Save a Copy.

* i18n(hu, tr): translate the OpenRaster save notice
main added complete Hungarian and Turkish catalogs after this branch
was cut, so every_tl_literal_is_translated needs their rows for the
two new strings. Wording follows each catalog: informal Hungarian
with "{name}" after a colon; formal Turkish with Biçim for format.

* i18n(sr): translate the OpenRaster save notice
Main gained a complete Serbian catalogue (#4436); every_tl_literal_is_translated
needs the notice's two strings there too.

Open and save .ora with pixel layers (any offset), nested groups, pass-through
groups, names, visibility, opacity, edit/alpha locks and blend modes (svg:* plus
Krita's krita:* names), at 8 and 16 bit. Save applies pixel masks, renders
text/shape/fill/smart layers to pixels and reports what OpenRaster can't hold.
Wired into File > Open/Save, the CLI, automation/MCP, the web picker and the
desktop file associations. Checked against 34 Krita 5.2.9-authored files
(opt-in krita_corpus test) and Krita re-opening our exports.
