* Place decodes, fits and renders in a background job
File > Place Embedded / Linked started with Session::start, and
Session::start_place_bytes for bytes with no path, now run the decode,
flatten, resize and SVG render on a worker (prepare_place) and insert the
layer when the job is applied (apply_place). Inline callers (execute, the
CLI, headless MCP, actions) behave and return exactly as before. Part of
#10031.
* Dropped and placed files no longer freeze the window on desktop
With background jobs on, File > Place and files dropped on the canvas start
the place as a job (JobsUi.place). Free Transform begins when the layer has
landed, a failed or cancelled place is reported and the drop queue goes on,
and a drop that arrives meanwhile waits for it. The place shows its progress
in the status bar instead of the modal dialog, so the view stays usable.
Part of #10031.
* Tests: compare place job results without the layer id
Layer ids come from a counter shared by every session, so a job and an inline place in two sessions never get the same one.
* Dropped files stay with the document they were dropped on
Each queued canvas drop now carries its document's id. A file is placed
only while that document is active: files dropped on a document in
another tab wait until it is back in view, and are discarded with a
message when it is closed. Web drops, read by the shell after the drop,
go to the document the drop landed on.
Before, the next queued file went into whichever document was active
when the previous place finished, failed or was cancelled, in the
background and inline paths alike.

* Place decodes and fits in the background: dropping a large file no longer freezes the window
Placing a file decoded, flattened and resized on the UI thread; a large PNG froze the
window for seconds (#10031). `place_bytes` is split into a session read, `prepare_place`
(decode, flatten, fit, translate, SVG render at placement scale) and `apply_place`, and
runs through `jobs::run`, so File › Place and canvas drops run on a worker with progress
and cancel. The window follows the job: status-bar progress, Free Transform when the layer
lands, and drops queued per target document.
Review fixes on the way:
- a path and byte drop queue entry records its target DocId, so files dropped on one
document never land in another after a tab switch, and closed documents discard theirs;
- the closed-document notice stays up for a frame instead of being cleared by the next
queued placement;
- the queue is bounded (32 files / 256 MiB) so drops waiting on another tab cannot grow it
without limit;
- flatten and resize stop at the job's interrupt, and a place skips the modal progress
dialog only when the status bar actually shows its progress;
- the placement's `doc` is kept only for SVG input, through the importer's `is_svg_input`;
- the interrupted-composite test uses an opaque fixture that varies by row and channel, and
checks the composite against the layer's stored pixels.
* Place reads its file in the job, and refuses a huge canvas as before
file.placeEmbedded and file.placeLinked read the whole file in the
command before the job started, so a path dropped on the canvas or
picked in File > Place still blocked the window for the read. The place
now carries the path and reads it in prepare_place: on the job's worker
in the background, on the calling thread inline (wasm, background jobs
off), with the same read_file limit and error text. Whether the source
is a vector one is decided once it has been read.
The job's flatten check returned Other("the document canvas is too large
to flatten"), where the place used to give flattened_checked's
BadParams for file.place naming the canvas size. Both now share
check_flattenable, so the old error type and message are back.

* Path drops aren't capped, and a discarded drop wakes the queue
The 32-file cap on the drop queue counted path drops, which hold no
file contents while they wait, so dropping 40 files on the canvas
placed 32 and refused 8 where main placed them all. The count cap now
applies to browser drops only (each holds its whole file); the byte
budget still bounds those.
When place_next_dropped discarded a closed document's files it returned
without asking for another frame, so another document's queued files
waited for the next input event. It now requests a repaint when files
remain, keeping the one frame that shows the notice.

One unreadable tile used to block editing, saving and exporting every open document
(spill::check_integrity was process-global). Add Tile/Surface/Document::scratch_health
(free while no tile has failed) and Document::for_each_surface (ops' history walk now
delegates to it). edit_with checks the document before and after, jobs the document they
captured, import the result, save/export the document written; check_since is now
generation-only so a failure or recovery during an operation refuses it once and a retry
works. Caches check their own sources and purge once per new failure instead of every
frame. Fault-injection tests use a duplicated handle (the Unix file has no name).
Resolve conflicts with main's prefs UI split, session/execute.rs move, GPU memory
budget (gpuMemoryMb, 0 = auto, kept from main) and effective_memory_usage_mb history
budget. Port the Memory Usage % and Scratch Disks preferences into prefs_ui, the edit
integrity guard into session/execute.rs, and adapt main's new pixel readers to the
guarded TileBytes API. Cargo.lock regenerated; scorecard regenerated.
* perf: reuse large buffers so a pinned glibc trim threshold costs no speed (#10479)
With MALLOC_TRIM_THRESHOLD_ set (#8743), glibc maps every allocation over
128 KiB fresh, so tiles, compositor bands and filter scratch were page-faulted
in on every call: viewport compose 3.6x slower, Gaussian Blur up to 1.8x,
.pcraft save 2.4x.
- photocraft_raster::scratch: a process-wide, capped pool of large Vec
buffers (u8/u16/f32/[f32; 4]). A miss drops the oldest buffers worth its
size down to a 256 MiB floor, so peak memory stays near glibc's defaults.
The engine releases the pool after any command that closes a document,
Headless::close does too, and an idle thread releases it after 2 s unused.
- Tiles, compose Buffer/masks/bands, algo Image and the blur paths, engine
adjustment/filter scratch, GPU tile upload and io import buffers go through
the pool.
- .pcraft save reuses one zstd FrameCompressor per worker (byte-identical).
- interactive_bench reports minor page faults per run.
36 MP, trim threshold set vs glibc defaults: viewport 5.6 vs 6.1 ms (was
22.7), Blur r4 445 vs 437 ms (was 852), Curves CPU proxy 35.0 vs 35.7 ms
(was 50), flatten 146 vs 147 ms (was 237), save .pcraft 251 vs 230 ms (was
545). RSS after closing a 5400x7200 document: 21 MB with trim set.
* fix: corpus tests build again; return remaining pooled buffers (#10479 review)
- Corpus-gated io tests and the Photoshop-oracle test moved `.px` out of a
`Buffer`, which now implements `Drop` (E0509 with `--features corpus`):
use `into_px()`.
- io: masks, the merged image, extra channels, smart-filter masks,
smart-object pixels and patterns give their `interleave` buffers back to
the scratch pool after writing them.
- compose: recycle the mask values of a pass-through group, `effect_shape`
and both `split_parts` callers.
- Styled Free Transform preview copies each band out instead of moving it,
so the band returns to the pool.
- interactive_bench: the fault count covers each whole run, untimed setup
included; say so.
