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.
