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.

* TIFF: BigTIFF, every IFD and SubIFD, banded parallel decode (FILE-215-8)
Large and multi-page TIFFs now open the way Photoshop opens them, quickly and without a second
full-size buffer, and any directory of the file can be opened on request.
* photocraft-codecs `tiff_ifd`: a bounds-checked directory walker for classic TIFF and BigTIFF
(LONG8 / IFD8, both byte orders). It follows the whole IFD chain and the SubIFD trees (tag
330) with a seen-set, a depth limit and a 10 000-directory cap, and checks every value range
against the file. `tiff_info` lists the pages (size, kind: page / reduced-resolution / mask,
parent, storage); `default_page` is the first full-resolution page of the main chain, so a
leading thumbnail is skipped. `decode_tiff_page`, `tiff_orientation`, `tiff_page_orientation`.
* Banded decode: the `tiff` crate reads the chosen directory through a patched byte view (header
-> that IFD, its next pointer -> 0, WhiteIsZero / palette -> BlackIsZero), so SubIFDs and
cyclic chains decode. The image is allocated once (fallibly, zeroed in parallel) and each
strip or row of tiles, across every plane, is decoded straight into it, in parallel on native
targets, with one capped chunk-sized scratch buffer per worker. New: planar configuration 2
(was an error), palette images (as RGB), 64-bit integers, associated alpha made straight,
non-alpha extra samples dropped. Image data cut off by the end of the file decodes with a
`Truncated` warning. Before the crate sees a file: structural tag values must lie inside it,
the chunk tables must match the geometry (checked in 64 bits; the crate overflowed and
panicked on `(h / rows + 1) * planes`), and a decompression-bomb guard refuses files far too
small for their declared size.
* WhiteIsZero and BigTIFF Orientation keep upstream #746's behaviour (#691, #693) through the
new decode path; regression tests cover both.
* Encode: `EncodeOptions::tiff_bigtiff` writes BigTIFF; without it, BigTIFF is chosen when the
file could pass 4 GiB (and a classic write that overflows 32-bit offsets is redone as BigTIFF).
* photocraft-io: `import_tiff_page(name, bytes, page)`; the TIFF branch of import goes through it.
* Tests: codecs `tiff_pages.rs` on hand-built files (`tests/common/tiffgen.rs`): BigTIFF LE/BE at
8/16/32f, padded tiles and planar strips/tiles, pages and SubIFDs, cycles, the IFD cap,
truncated and past-EOF strips, huge dimensions / counts / tiles, WhiteIsZero, palette, wide
formats, BigTIFF write, and a cut / bit-flip / random-mutation zoo (an ignored long run did
200 000 mutations without a panic); io `tiff_pages.rs`. The `decode_tiff` fuzz target walks
every page. `tiff_bench.rs` (ignored) times a 30 MP decode against the previous path.
* 30 MP RGB (release, 16 threads, same run): Deflate 344 -> 32 ms, LZW 428 -> 43 ms, 16-bit
Deflate 497 -> 46 ms, uncompressed 15 -> 10 ms, 256 px tiles 36 -> 10 ms, planar error -> 12 ms.
* Scorecard FILE-215-8 done; README and roadmap updated.

* 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`.
