* Make large pixel operations allocation-fallible
* Warp: drop the fixed 400 MP cap; fallible reservations already cover large transforms

* fix(compose): Preserve native CMYK fills through PSD round trips
Share depth-quantized ink samples between rendering and PSD caches.
Use the document profile for RGB fill colours and preserve valid imported
caches. Uncached CMYK fills use CPU rendering.
Cover all sample depths, gradient styles and tiled renders. Fix the real
16-bit gradient round trip and raise the psd-tools floor from 307 to 308.
* perf(raster): Reuse exact 8-bit CMYK conversions within rows
Cache the previous ink bytes and ICC result per row, with alpha decoded
independently. Keep the 16/32-bit conversion loops unchanged.
Matched 1 MP reads improve by 77% for smooth ramps, 33% with dithering
and 10% for random colours. Bitwise regression coverage includes all
depths, alpha and tile boundaries.
- A layer about the canvas's size keeps its whole effect region even where it overhangs the
edge, so the region keeps its size while the layer is dragged and the GPU moves its effect
maps with it instead of rebuilding the shape, distance fields and every effect each frame.
- Surface::translated moves a surface by copying encoded tile bytes tile to tile (no float
round trip, no full-size intermediate; whole-tile moves share the tiles): 2.3x faster than
to_interleaved + write_interleaved. Used by layer.translate, Move tool drags and
algo::resample::translate_surface.
- perf_scenarios: Move tool drag frame rows (styled layer, full-canvas layer with and without
a drop shadow).

Surface::fill_rect materialized every tile it touched, so a new document's
background cost one 256x256 tile per tile slot: ~360 GB for the 300000x300000
size the command accepts. Fully covered tiles now share one Arc'd tile, so a
solid fill costs one tile plus the tile index; edge tiles are written as
before, and copy-on-write splits a shared tile off when it is edited.
* Test: retry the GPU startup sentinel check while a forked child briefly shares the lock
monitor_profile tests spawn osascript in the same binary; between fork and exec the child holds
a copy of the marker file descriptor, so flock reports WouldBlock and begin() returns Busy.

- Real crash: build_engine_data took its template from the PSD's text
engine data and did expect("EngineDict"), so a text layer whose engine
data lacked EngineDict (or wasn't a dictionary) crashed PSD export.
The template is now repaired; regression test
engine_data_template_without_engine_dict.
- color: the built-in CMYK<->sRGB transforms fall back to the naive
formulas instead of expect if they ever fail to link.
- doc: insert_above falls back to the top of the root instead of
expect("valid path"); next_layer_name searches a bounded range.
- paint: Mips::new loops with while-let instead of last().expect.
- All eight crates deny unwrap/expect/panic/unimplemented/todo/unreachable.

Rust 1.99's clippy adds chunks_exact_to_as_chunks and some_filter, which
broke the Clippy step on every CI runner (it uses the latest stable). All
sites are mechanical: as_chunks drops the remainder exactly like
chunks_exact.
