heic-rs 0.1.2 to 0.1.4 fix six panics on malformed files, found by fuzzing:
four in release builds (a uuid box too small for its extended type, a
block starting right of the picture, a conformance window larger than the
picture, and a reference row below the picture) and two with overflow
checks on (a PCM bit depth above the sample bit depth, a slice QP out of
range). The API, MSRV and output are unchanged.
Both pins move together: crates/heif and the codecs fuzz target, which
calls heic-rs directly. guarded() stays as the backstop it was meant to be.
* feat(codecs): decode every frame of an animated GIF (#572)
decode_gif_frames returns each frame composited onto the logical screen
(disposal methods applied) with its delay in milliseconds. decode still
keeps the first frame only. A damaged later frame keeps the frames before
it and marks the first with DecodeWarning::Truncated; dimensions, the
total decoded bytes and a frame cap are checked against the limits.
* feat(io): import_gif_frames hands each GIF frame over as a document (#572)
A frame at a time becomes a single-layer document, so a caller can
flatten and drop it instead of holding every frame twice.
* feat(engine): animated GIFs load every frame into video layers (#572)
New Video Layer from File, Replace Footage, Reload Frame and Video Frames
to Layers take all frames of a GIF instead of the first. The timeline rate
comes from the GIF's delays (the most common one, delays under 20 ms shown
at 100 ms as browsers do); an explicit fps still wins.

* Open HEIC/HEIF photos (#355)
iPhones save HEIC by default and Photoshop opens it; PhotoCraft had no
HEIF code, so .heic was missing from File > Open and failed to decode.
Add Format::Heif to photocraft-codecs, decoded by heic-rs (pure Rust,
forbid(unsafe), MIT OR Apache-2.0, wasm-ready): single pictures and
grid-tiled photos, 8-bit to U8 and 10/12-bit to U16, auxiliary alpha,
ICC, EXIF and XMP. The container's irot/imir/clap are applied and EXIF
Orientation is rewritten to 1, so photos are never turned twice. Limits
are checked against the declared size before decoding. Read-only (no
pure-Rust HEVC encoder), listed in ASYMMETRIC_EXCEPTIONS.
File > Open (desktop, web) and the batch list accept heic/heif/hif.
Tests compare against Apple's own decode and a 16-bit source, cover
orientation, metadata, limits and every truncation; fixtures from
heic-rs and pillow-heif are attributed in ATTRIBUTION.md.

* HEIF: pin heic-rs exactly and add a decode_heif fuzz target
Review follow-up: heic-rs is young and parses untrusted files, so pin it
(=0.1.1) and fuzz the HEIF path. The target covers both orientation
paths and is meant to run with -timeout so a hang is reported, not
only a panic. It is added to the CI fuzz matrix.

* HEIF: a heic-rs panic is a malformed-file error, not a crash
Fuzzing decode_heif found two out-of-range slices in heic-rs 0.1.1 on
malformed files:
- in its box parser (boxes.rs:130), reachable from a 72-byte file, even
through the metadata-only probe;
- during HEVC reconstruction (hevc/decode/recon.rs:70).
The background job path catches panics, but the synchronous ones (jobs
off, the CLI) did not. The HEIF codec now runs the decoder under
catch_unwind and reports a panic as CodecError::Malformed, as
gpu/health.rs already does around wgpu.
The fuzz target also calls heic-rs directly, so its panics still reach
the fuzzer. The 72-byte input is a regression test, which fails
without the guard.

* HEIF: move the decoder into an optional photocraft-heif crate
The heic-rs decoding from #372 now lives in `crates/heif` (photocraft-heif, standalone, depends
only on heic-rs =0.1.1): probe, decode with a pixel limit, container transforms, alpha, 8/10-bit,
ICC/EXIF/XMP and the catch_unwind guard, behind a small API of its own (Info, Options, Decoded,
Error). photocraft-codecs uses it behind a new non-default `heif` feature; the apps and
photocraft-io forward it. HEIF detection, extensions and mime stay compiled in, so without the
feature a HEIC file is still recognised and opening it is a clear "HEIC/HEIF support isn't
included in this build of PhotoCraft" error. `cargo xtask layers` allows exactly codecs -> heif
between standalone crates.
The fixtures are no longer committed: `cargo xtask corpus --heif` fetches them from heic-rs
(tests/fixtures, v0.1.1) and pillow-heif (tests/images) at pinned commits, verified against
xtask/heif-corpus.sha256 (same bytes as the PR's copies). The fixture tests run with
`--features corpus,heif` (`cargo xtask test-corpus` enables both).

* Build CI and official binaries with HEIC support (--features heif)
CI test and clippy, the FreeBSD job, and the macOS, Linux (and Flatpak), FreeBSD, Windows and
web packaging all build with the `heif` feature; CI also tests codecs/io without it on Linux so
the "not in this build" path stays covered. `cargo xtask wasm` also checks photocraft-codecs with
`--features heif`.
