Portable fork

This fork (ModderMule/specialdlp) builds the same SDC rules as a cross-platform shared library (Windows, macOS, Linux; x64 and arm64) for eMuleQt. The rule code in specialdlp/specialdlp/antiLeech.cpp stays as close to upstream as possible so upstream updates merge cleanly. ATL/shlwapi are replaced by sdlp_compat.h.

• C ABI: see include/specialdlp.h.
  • UTF-16 strings and extern "C" functions with an sdlp_ prefix.
  • The ABI version is checked at load.
  • Each check returns NULL for a clean client, or a reason string in static storage.
• Variants: one binary for all of them. Select one at runtime with sdlp_set_variant() (lite, all-verycd, easymule, verycd-nickname or verycd-tag), instead of shipping one DLL per variant.
• Not compatible with the Xtreme antiLeech.dll exports: DLPCheckNameAndHashAndMod took MFC CString, which cannot cross a portable ABI.
• Unbuilt leftovers: specialdlpTester (Windows/MFC) stays in the tree as a reference, but is no longer built.

Build and test:

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release
ctest --test-dir build -C Release --output-on-failure

Test coverage:

• tests/vectors.tsv holds positive and negative cases for every rule.
• On Windows, CI also builds the original upstream DLLs and checks that the port returns the same result for every vector, for each variant.
• Tagged builds (v*) publish per-platform archives plus SHA256SUMS.txt.
