fbe5f80ba4 PSD: read smart-filter masks (FEid) with one section per smart object (#396)
* PSD: read smart-filter masks (FEid) with one section per smart object

Photoshop writes the global Filter Effects block (`FEid`/`FXid`) as a
version followed by one length-prefixed section per filtered smart
object, each padded to 4 bytes outside its length. The reader took the
first section's length as the whole body, so any document with two or
more filtered smart objects failed with "filter effects: N unexpected
bytes after the data": the smart filter masks were not imported and the
open reported a warning. The 28 FEid files in the public corpora each
hold a single section, which is why the corpus never hit it.

The reader now walks every section (still accepting several items in one
section, as earlier PhotoCraft versions wrote), and the writer emits one
padded section per item, as Photoshop does.

Tests: reads_one_section_per_item (fails before: parse error) and
reads_several_items_in_one_section; malformed_data_is_an_error now cuts
only before the end of the section.

* PSD FEid: an empty item list still writes one section, so it reads back

BFlatandClaude Opus 5.5 2868220032 Formats: deep .pcraft groups reopen; zero-size PSD rejected; JPEG mattes over white; no-ICC formats get sRGB (#517, #519, #521, #522) (#555)
* PSD: reject a header with zero width or height (#519)

A 0xN header opened as an empty document and saved back as another
zero-sized PSD or .pcraft. Header::validate now requires at least 1x1
(the spec range starts at 1), and PSD export validates the header so a
zero-sized canvas is never written.

* .pcraft: documents with deeply nested groups load again (#517)

serde_json's 128-level recursion limit made bundles with 40 or more
nested groups unreadable after a successful save. The manifest is now
parsed with that limit disabled behind a linear JSON depth check, layers
are decoded and converted one level at a time with small stack frames,
and groups may nest up to MAX_GROUP_DEPTH (100) levels, which load and
save within a few hundred KiB of stack. Saving a deeper document fails
instead of writing a bundle that can't be opened.

* Export: convert non-sRGB RGB to sRGB for formats without a profile (#522)

GIF, BMP, QOI, TGA, ICO and Netpbm can't embed ICC, so a linear-light
or Display P3 document was written with values that only meant something
under the dropped profile (a linear EXR came out dark). export_flat now
converts such RGB to sRGB through photocraft-cms (perceptual, as Quick
Export does) for every photocraft_io::export route. The EXR/HDR linear
conversion shares the same banded helper.

* Export: composite transparency over white for formats without alpha (#521)

The CLI, MCP, Save As, Layers to Files and Layer > Export As dropped the
alpha channel when writing JPEG (or Radiance HDR), exposing the colours
stored under transparent pixels, while Export As and Quick Export
composite over white. export_flat now flattens over white too (no ink
for CMYK) and says so in its warnings.

Brandon ThomasandClaude Opus 5.5 d881785fde Photoshop brushes: .abr import, stylus pressure/tilt, 36 grouped presets, .grd import (#74)
* psd: .abr brush (v1/v2/v6+) and .grd gradient (v5) parsers and writers

Clean-room from public format descriptions: legacy computed/sampled brushes,
8BIM-sectioned samp/patt/desc files, 8/16-bit raw and PackBits tips. Bounded
(MAX_EDGE, MAX_TOTAL_BYTES), damaged brushes are skipped with warnings, hostile
input returns Err. Adds an abr fuzz target.

* paint: 36 grouped built-in brush presets and new procedural tips

General / Dry Media / Wet Media / Special Effects groups (pressure size/opacity
variants, airbrush, pencils, charcoal, pastel, crayon, rake, watercolour, ink,
oil, foliage, grass, stipple, sparkle, halftone…). Leaf, grass, charcoal,
sponge, star and rake tips are generated in code. BrushPreset gains a group.

* io: map .abr brushes onto BrushSettings

Tip shape, shape dynamics, scattering, texture (embedded patt patterns),
dual brush, colour dynamics, transfer, pose, noise, wet edges, build-up and
captured tool options; unmapped settings are reported as warnings. Includes
bench_abr (100-brush import, 5000-dab stroke).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* engine: brush.presets.importAbr and gradient.presets.importGrd

Path or base64 data, group per file (re-import replaces), unique names next to
the built-ins; graceful-failure tests.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* ui: real stylus pressure/tilt, grouped Brushes panel, Import Brushes

Pen force from egui Touch events (Windows WM_POINTER via winit), Pointer Events
pressure/tilt/twist on the web, tilt via ui.pointer; mouse stays 1.0. .abr/.grd
open from File > Open, drag-and-drop, Brushes panel and Preset Manager. Preset
previews keyed on a cheap signature instead of the full brush JSON.

Brandon ThomasandClaude Opus 5.5 69f0e25d5f Never crash: psd, codecs, format, io are panic-free (Rule 9) (#34)
- codecs: bump tiff 0.10 -> 0.11. tiff 0.10 indexed an empty SampleFormat
  list and panicked on a crafted TIFF (found by mutation fuzzing);
  regression test tiff_empty_sample_format_is_an_error.
- codecs: Image::new returns Result instead of panicking on size overflow.
- format: par_compress returns an error if a compression worker panics.
- io: par_map joins every worker before relaying a worker panic, so the
  thread scope can't panic on an unjoined thread.
- All four crates now deny unwrap/expect/panic/unimplemented/todo/
  unreachable outside tests.

Brandon ThomasandClaude Opus 5.5 1c09936154 Clippy 1.99: chunks_exact with a constant size -> as_chunks; drop a no-op Option filter
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.

Brandon ThomasandClaude Opus 5.5 f7eb6ea9e7 Format: adopt the craft-family rustfmt.toml and format the workspace
CI's `cargo fmt --all -- --check` has failed on every run because the
repo had no rustfmt config and was never formatted. Use the same settings
as EffectCraft/FilmCraft (max_width 160, use_small_heuristics Max), which
also keeps the churn small. Formatting only; no code changes.
