Add YAPF version 2: texture container with GPU blocks and metadata

 		YAPF 2: texture container with GPU blocks, wide samples and streaming 
Adds format version 2 alongside version 1 (still written for plain 8-bit
images, so existing readers keep working). Full specification in
docs/FORMAT.md.

- GPU block payloads: BC1-BC7, BC6H, ETC2/EAC, ASTC 4x4-12x12, in tiles
  of 16x16 blocks. Built-in BC1/BC3/BC4/BC5/BC7/BC6H encoders and
  BC1-BC7 decoders (BC6H/BC7 bit-exact with a reference decoder).
- Lossless 16-bit, half and float pixels as byte planes over the 8-bit
  coder; order-preserving float mapping, transforms at sample width.
- Cubemaps, cube arrays, texture arrays, volumes, animation frames.
- Channel meanings, normal convention, linear mask, primaries/transfer,
  mip filter and coverage-preserving mips (yapf_tex_build_mips).
- Small mips stored first, file size in the header, surface/tile tables:
  decode from a file prefix and single tiles (virtual texturing).
- yapf-sum checksums on header, tables and every tile; needs bits so
  decoders refuse cleanly what they cannot read.
- Optional entropy stage: per-surface Huffman code books with a
  neighbourhood context (~10% smaller photos) and per-lane packing of
  GPU blocks (~3x smaller on disk); planes decoded interleaved.
- Notes: author, licence, source, tool, ICC and application tags.
- CLI: --format, --entropy, --coverage, --normal, --map, colour options,
  16-bit/HDR input, pack cube/array/volume/anim, info, verify, export.
- Tests for all of the above, including fuzzing; v1 API reads 8-bit v2.

YAPF v1: fast byte-aligned format, SIMD, tools and plugins

d7f494a0c9 Language bindings, KDE thumbnails, yapf compare, in-memory encoding 
- yapf_encode() / yapf_free_buffer(): encode to memory; yapf_save uses it
- yapf.c also compiles as C++
- `yapf compare`: size and decode speed of the original format vs YAPF,
  with a lossless check
- bindings with tested examples: C++ (header-only), C# (P/Invoke),
  Rust (crate, builds the C code), Go (cgo), Java (FFM API, Java 22+),
  Zig (@cImport), LuaJIT (FFI), TypeScript types for the JS port;
  Python now encodes in memory
- docs/LANGUAGES.md and examples/ with measured results
- KDE Dolphin thumbnail plugin (KF6, CMake)
- README: honest status for Photoshop / VS Code / Figma (not run in the
  apps yet) and macOS (cross-compiled only), platform table

2ca726e3af YAPF v1: fast byte-aligned format, SIMD, tools and plugins 
Format (version 1, replaces the earlier experimental versions):
- per-tile YCoCg-R or subtract-green colour transform, 8-bit modular
- 12 row filters per 8-row band (Left, Gradient, Up-right, Up-average,
  Up 1-8 rows), none with more than a one-add serial dependency
- residuals in groups of 8 at the group's width (w bits x 8 = w bytes),
  4-bit control codes with repeat-previous-width runs chosen by DP
- constant and stored tiles, independent 64x64 tiles, mips, GPU hints
- all sizes validated before decoding; corrupt input is rejected

Library:
- SIMD on by default: SSSE3 (runtime CPUID check; GCC, Clang, MSVC,
  MinGW) and NEON on ARM64; -DYAPF_NO_SIMD for plain C
- yapf_load_memory, yapf_load_mt, yapf_load_memory_mt
- 6-10x faster decoding than PNG (stb_image) on one core; -O2 and -O3
  builds perform the same
- fixes for macOS (sysconf) and the Windows import library exports

Tools and integrations:
- `yapf` CLI: convert PNG/JPG/TGA/BMP/PSD/GIF <-> YAPF, info, bench,
  thumbnail, mips
- JavaScript and Python bindings (byte-identical to the C encoder)
- GIMP 3 plugin: exports the flattened image, optional mipmaps
- Blender extension: import (also as plane), export, drag and drop
- VS Code preview, Figma plugin, Photoshop scripts, Linux MIME type and
  thumbnailer
- Makefile, updated build.sh / build.bat, tools/build_release.sh
- tests/test_yapf.c (784 checks) and bindings/js/test.js
