The desktop app keeps logs/lightcraft.log in its settings folder (#286)
and a failed start names it (#370), but a user still had to find the
folder by hand. The host now hands the UI its log file (Services
.log_file) and Help ▸ Open Log Folder (app.openLogFolder) reveals it
through the existing reveal service: Finder and Explorer select the
file, Linux opens the folder. Off where no log is kept (the web,
--memory, LIGHTCRAFT_NO_PREFS). Translated in de, es, ja, pt-br, ru,
zh-hans and zh-hant; parity row MENU-HELP-LOGFOLDER; What's New and
README note it.

With Shader Cache Size disabled in NVIDIA Control Panel, the driver walks
the whole system drive inside D3D12CreateDevice (traced by the reporter
to NvMemMapStoragex.dll!TotalDiskUsage), before the window's first
frame; Driver Default fixes it (confirmed in #374, PhotoCraft too). The
launch-argument walk found on the way was fixed in #394.

The desktop showed rfd's synchronous dialogs on the UI thread, so the
window stopped answering the compositor while one was up: GNOME marked
LightCraft "not responding", the File menu stayed drawn and the control
channel went quiet. Services.picker lets the host start a dialog
elsewhere and answer through a channel; a command that needs a path
asks for one and returns, and runs again with the answer when the
dialog closes (pick.rs). Import Photos, Import from Folder, Open
Library, Import Lightroom Catalog, Find Missing Photos, the preset and
curve-preset imports and exports, Auto-Tag from Tracklog and Locate
Missing File use it; hosts without a picker (the web, tests) keep the
synchronous dialogs. ui.inspect lists the waiting commands as
fileDialogs. Same cause as storytold/photocraft#574.

A full-size load asks the decoder for the largest box (`SourceLevel::Full` is
`usize::MAX`, cast to `u32::MAX`). `jpeg::decode` then computed `2 * u32::MAX` to
decide on DCT scaling: an overflow panic in debug builds (caught, so every
full-size JPEG load failed with "decoder panicked"), and a wrap that happened to
give the right answer in release. The comparison saturates now, and the engine
converts its `usize` edge with `u32::try_from` instead of a truncating `as`.
Found decoding camera JPEGs (no JFIF/EXIF header) at full size.

Lightroom Classic reads `ToneCurvePV2012Red/Green/Blue` only together with
`ToneCurvePV2012`: a packet with a channel curve and no master curve leaves the
photo unchanged there (rendered on a chart: the channel curve alone has no
effect, with an identity master curve it applies). Imports now do the same.
The preset-packet test helper uses made-up as-shot values.

XMP presets usually say LensProfileEnable=0, which turned optics.lens_profile
off and with it the DNG-embedded WarpRectilinear / FixVignetteRadial
corrections (iPhone ProRAW and other files that carry them). Lightroom
applies a file's built-in corrections whatever that switch says (our
inference), and LightCraft's profile corrections are only those embedded
ones, so crs import now carries over only an enabling switch. The Enable
Lens Corrections checkbox and the amount sliders keep working as before.

XMP presets carry fields that describe the preset or the photo rather than
an adjustment (Cluster, SupportsAmount2, RequiresRGBTables, SortName,
Description, CropConstrainToWarp, OverrideLookVignette, AsShotTemperature /
AsShotTint). preset.import listed them as settings that couldn't be carried
over; so did an HDREditMode of 0 and PointColors slots that are all -1.
They are now treated as bookkeeping; an HDR edit, a used Point Color slot and
unknown adjustments are still reported.

clippy 1.98's manual_chunks lint fails `cargo xtask ci` on main at psd.rs:170/191/201
(chunks_exact with a constant size). The fixed-size chunks also drop the per-sample
indexing. No behaviour change; the codecs tests pass.

CR2 and PEF decode without a camera colour matrix, like ARW, NEF, RW2,
RAF and CR3, but camera_preview::file_local_look (and the catalog's
relative white balance) left them out, so they rendered with the neutral
fallback matrix: the camera preview showed first, then a flat,
desaturated render replaced it. They now use the same guarded fit and
relative WB; a fit that fails the gates keeps the fallback, so a file can
only stay as it was or move closer to its camera JPEG. Not measured on
the corpus here (raw.pixls.us is blocked from this environment).
RENDER_CACHE_VERSION 15 re-renders cached CR2/PEF thumbnails.

egui keeps a popup inside the window, so a menu taller than the room
under the bar (Photo, on a short window) was slid up over the bar: the
titles vanished under it, and the pointer left on the title rested on
the first row and opened its submenu by itself. Every level now gets
the room it has below the bar (a submenu: from its row down, or up to
the bar when egui opens it upward) and scrolls inside it, with wheel,
drag and ▲/▼ strips that scroll while the pointer rests on them, as in
PhotoCraft's menu bar (storytold/photocraft#337). Menu levels and
submenu rows are registered for the control channel and tests.

The fixture wrote each row as one literal run of w bytes, which PackBits
can't express past 128 (a 160-pixel row's header byte read as a repeat
run). The old decoder clipped such rows silently; with the PSD fix in
this batch an overrun is an error, as it should be, and the fixture now
splits rows into valid runs.

A tiny hostile PSD could abort the process on out-of-memory in
`psd::decode` (allocation failure doesn't unwind, so catch_unwind
can't save it):
1. The RLE row byte-count table (channels x rows entries, from the
header) was reserved with Vec::with_capacity before checking that
the file holds it: 56 channels x 2^30 rows asked for ~480 GB from a
~40-byte file. The table is now taken as a slice of the input with
checked size math and read lazily, so nothing is allocated from it.
2. RLE rows were zero-padded / run-expanded to the declared width with
no tie to the input size, so all-zero row counts on a 1 Gpx (the
DecodeOptions::max_pixels limit, already enforced by check_size)
32-bit image expanded to 4 GiB per channel. A PackBits row expands
at most 64x (2-byte repeat run -> 128 bytes), so each decoded row
must now declare at least ceil(row_bytes / 128) * 2 encoded bytes,
and the decoded channels' data must be present in the file, before
any plane is allocated. Decoded planes are thus bounded by 64x the
file size as well as by max_pixels. PackBits now decodes into a
pre-sized, zeroed row and a run that would write past the declared
width is an error instead of being silently clipped.
Also: size math (width x height x bpc, samples) is checked; image
buffers are allocated with try_reserve_exact (TooLarge on failure);
only the colour (+ alpha) planes are decoded, extra channels are
skipped; the PSB layer-section length no longer truncates on 32-bit
targets; interleaving uses iterators instead of indexing.
Valid PSDs (raw and RLE, 8/16/32-bit) decode identically; regression
tests cover a huge RLE header with a truncated table (aborted with a
481 GB allocation before), all-empty RLE rows, counts larger than the
file, a repeat run past the row width (was Ok before) and a 16-bit
gray RLE file with an extra channel.

The import probe of a non-raw image decoded it (at a 64 px fit, which for
JPEG still entropy-decodes every block and for PNG inflates everything)
only to learn its stored size and orientation: ~95 % of import CPU.
lightcraft-codecs gets `read_header(bytes) -> Header { format, width,
height, orientation }`: JPEG from its markers (EXIF orientation), PNG from
its chunks (IHDR, eXIf anywhere), TIFF from the first IFD (tiff crate,
no strips read), WebP from its RIFF chunks / bitstream header (image-webp),
PSD from its header and image resources. GIF, BMP and JPEG XL keep the
small decode. `files::probe_bytes` uses it; raw handling is unchanged.
The TIFF colour-layout check is shared with the decoder (`layout`).
Measured (release, 4 cores, throwaway benchmark, per file, bytes in
memory): 200 generated 4000x3000 JPEGs (3.6 MB): 72.7 ms -> 2.1 ms
(read_header alone 1.05 ms; the rest is the content hash and metadata);
20 PNGs (30.8 MB): 236-265 ms -> 9.0-9.6 ms.
Corrupt files (behaviour note): the header readers also refuse what a
decode refuses before the pixels (unsupported layout, compression, frame
type, bad IHDR, ...) and truncated files: a JPEG whose markers don't reach
its EOI, a PNG cut before the chunk after its IDAT run, TIFF strips/tiles
that start past the end, a WebP image chunk or PSD merged data past the
end. So truncated files (interrupted copies, partial downloads) are still
marked `error` in the import review, as before; tests check that whenever
the old decode accepted a (cut or byte-mutated) file the header agrees.
Changed: damage *inside* compressed data that is all present (flipped or
garbled bytes) was refused at scan and is now imported, and shows as
unreadable ("!" in the grid) when rendered. Also: tiny JPEGs (< 128 px)
were decoded leniently by the old probe, so a truncated one imported; it
is now refused. A TIFF truncated inside its last strip is not detected
(StripByteCounts are often overstated, so only strip starts are checked).
Tests: header readers vs decode on generated JPEG/PNG/TIFF/WebP/PSD/BMP
with and without EXIF/TIFF orientation; truncations and random mutations
agree with decode; hostile headers (zero/absurd sizes, bad lengths,
truncation, garbage) are errors; read_header added to the fuzz tests;
probe_bytes oriented dims match the decode-based values.

C-RAW is quantised wavelet coding: next to clipped highlights its
reconstruction overshoots the sensor range by a few quantisation steps.
On 17 CC0 CR3 files (SX70 HS, G5 X Mark II, M6 Mark II, EOS R, RP, 90D,
M200, R5 Mark II, R6 Mark II, R6 Mark III, R8) samples reached 16384 to
16419 at 14 bits, never below 0, and decoding failed with "decoded
sample outside its bit depth". Lossless files of the same bodies clip at
exactly 16383. Wavelet samples are now clamped to the CMP1 bit depth;
lossless samples outside it are still corrupt data.
The other 93 CR3 files have no sample outside the range and render
pixel-identically. Render cache version 13 -> 14.
scan_for_jpeg walks every JPEG-like start in a container it can't parse;
each walk runs through the marker segments that follow (up to 4096) and
their entropy data. A crafted CRW/MRW/X3F (or unsupported TIFF raw) of
fake starts one after another makes every walk cover most of the file:
quadratic, about a minute for 40 MB, on the import's probe thread. The
walks now report how far they read and share a budget of eight times the
file's size (at least 1 MiB); real files' candidates fail within a few
bytes or are the preview itself. Test: 200,000 fake starts, 0.15 s.
