floret: add recipe for floret 0.10.5

Add a new recipe for floret, a fastText fork with Bloom embeddings
for compact, full-coverage vectors compatible with spaCy. Builds
shared library, static library, and CLI binary via CMake with zlib.

Includes a cross-compilation patch (CMake 3.5, <cstdint> for GCC 15.x)
and installs the shared library under its real SONAME to keep
libfloret.so as a symlink.
