* Import Affinity issue 1606 special shapes
* Affinity corpus: give the #1606 sample ceilings a margin for font differences between machines
The samples' labels render with whatever fonts are installed, so the measured
differences move by up to 0.8 between machines; each ceiling is now the higher
measurement plus about 1. Also use as_chunks in on_white (clippy with --features corpus).

The maintainers approved the new crate, its fuzz targets and the corpus
upstreams in principle (storytold/photocraft#1607), so this undoes the
interim opt-in: ci.yml fuzzes preview and import_preview again, corpus
--all fetches the Affinity set, and its test runs under the normal
corpus feature. The provenance section stays.

Review on storytold/photocraft#1607 asked maintainers to decide on new
fuzz targets in ci.yml and four third-party corpus upstreams in
corpus --all. Until they do, neither touches CI: ci.yml is main's again
(the targets stay in crates/affinity/fuzz, run locally), and the
Affinity corpus is fetched only by corpus --affinity and tested with
--features corpus-affinity, so --all and test-corpus are unchanged.
The plan is to move those files into photocraft-corpus.
The crate README now spells out the provenance: no Affinity software,
afread's MIT description re-described without translating code, every
structure confirmed on public files (CRC-32 per entry, self-typed
fields), semantics fitted to Affinity's own thumbnails, and how the
sample documents were licensed.

photocraft-affinity now reads native Affinity documents (container
versions 8-12): the FAT and revision chain, stored/zlib/zstd entries
with predictors and CRC checks, the tagged object stream in doc.dat,
and the document model (pages, artboards, layers, groups, curves,
geometric and compound shapes, fills, gradients, strokes, text, placed
images, pixel layers, masks and embedded-document caches). Every size
is bounded and malformed input returns an error.
photocraft-io maps it to an RGB8 document with artboards, groups, shape
layers, type layers, embedded smart objects, pixel layers and
vector/layer masks; what can't be mapped is listed in the warnings. The
embedded preview is now only a fallback when the native data can't be
read, and only that preview is refused by Place and warningless imports.
`cargo xtask corpus --affinity` pins 21 public CC0/MIT documents,
sha256-verified; the io corpus test compares each import with the
thumbnail Affinity saved in it (mean difference 0-4.6 of 255).
Affinity export is not implemented: no Affinity installation was
available to validate written files.
