fix(compress): resolve clean code warnings and fix memory pool bugs

- Replace deprecated C++ headers and unsafe memcpy/memset/memmove
- Add missing header guards; wrap multi-statement macros in do-while(0)
- Zero-initialize ts_header_t; pass array lengths to satisfy bounds checks
- Extract FixedRatio/DataType enums to compress_types.h
- Remove unused FSE/HUF/Bitstream source files (not invoked by current path)
- Fix: throw bad_alloc on posix_memalign failure and pool exhaustion
- Fix: skip submitting corrupted data on compression failure
