v0.11.2

• Fixes subsampled JPEG 2000 decoding with nonzero image origins at reduced
  resolutions and for cropped regions, including the wsi-rs fuzz reproducer.

• Improves JPEG entropy decoding, extended and lossless sample output,
  progressive scan handling, and AArch64 NEON conversion and IDCT.

• Improves native bitplane scanning and full-resolution subsampled placement.

• Improves grouped JPEG Metal decode, pooled output reuse, HT cleanup,
  and inverse wavelet transform dispatch with regression coverage.

• JPEG DCT-scaled decodes (1/2, 1/4, 1/8) now match libjpeg-turbo, and
  therefore OpenSlide's NDPI/VMS levels, bit for bit. Checked against a
  committed libjpeg-turbo 3.1.4.1 reference matrix covering every chroma
  layout, restart intervals, progressive scans and 12-bit precision:

  • Reduced IDCTs round like libjpeg's DESCALE instead of truncating.
  • Each component gets libjpeg-turbo's IDCT size: 4:2:0 and 4:1:0 chroma is
    decoded with a larger reduced IDCT, so 4:2:0 needs no upsampling below
    full size.
  • Chroma is replicated instead of smoothed at 1/8 scale, and at any scale
    (including full size) when 2:1 chroma is at most two samples wide.
  • Progressive images apply the reduced IDCT to their coefficients instead
    of decimating a full-size decode.
  • 12-bit images use 12-bit reduced IDCTs instead of decimating a full-size
    decode. 12-bit 4:4:0, 4:1:1, 4:1:0 and 1x4 layouts still return
    NotImplemented.

• Fixes a panic in 12-bit region decodes when the region excluded image
  blocks on its left or right.

• Includes output rows in the 12-bit scratch budget so tall, narrow JPEGs
  decode without false memory-cap failures.

• j2k-jpeg-cuda CPU-backed scaled and region-scaled surfaces now have the
  scaled dimensions; they were sized from the source rectangle.

• JPEG Metal scaled decodes follow the same rules, and 4:2:0/4:2:2 region
  decodes keep the neighbouring chroma their smoothing reads when a region
  ends inside the image. JPEG images at most four pixels wide with 4:2:0 or
  4:2:2 chroma are no longer Metal or CUDA fast shapes: explicit Metal
  requests reject them and automatic routing decodes them on the CPU.

• Upgrades fearless_simd to 1.0.0 for the j2k-jpeg AArch64 NEON kernels
  and the optional j2k-native simd feature. The dependency is private, so
  public APIs are unchanged. j2k-jpeg keeps its private exact-AVX2 token on
  x86-64 because fearless_simd::Avx2 still represents the broader x86-64-v3
  feature set.

Release validation passed for the tagged source:

• Hosted CPU, API, package, and release checks.
• Full CUDA and Metal hardware validation.
• The release verifier validated all five attached T.803 reports for CPU on Linux, macOS, and Windows, plus CUDA and Metal.
