A CMYK document with several layers, masks or effects is flattened through the
RGB compositor. Its TIFF and JPEG exports were written as sRGB RGB, losing the
document's mode and ICC profile. The composite is now converted back through the
document's CMYK profile (relative colorimetric with black point compensation)
inside each parallel worker, written as four ink channels plus straight alpha at
the document depth, and tagged with that profile (the built-in coated CMYK
profile when the document is untagged). Invalid, non-CMYK or unusable profiles
are rejected. RGB-only formats keep the direct sRGB composite, and a single
plain raster layer keeps its native samples.
This fixes the output mode and tagging only: the RGB roundtrip does not
preserve original ink separations, black generation or CMYK-native blending.

Agents read the tool description, not docs/mcp.md, and the command_batch
description only said it stops at the first error. It now also says the
steps run in order and that earlier successful steps stay applied: there
is no rollback. docs/mcp.md gives the stop_on_error default and a recovery
recipe: inspect with doc_inspect, undo with edit.undo once per history
entry (undo does not reverse files written to disk), or experiment on a
copy made with image.duplicate or history.newDocument. A test checks the
listed description.

`hasMask` in document inspection covers only raster masks, so a layer
with a vector mask looked unmasked to an agent. Layers, groups included,
now also report `hasVectorMask` and `vectorMaskEnabled` (null when there
is no vector mask). `hasMask` keeps its meaning.
