Pull request overview

This PR modernizes the algorithm library: it replaces C-style headers with C++ counterparts, swaps C-style casts for static_cast, moves internal symbols from namespace detail into anonymous namespaces with ATFW_UTIL_SYMBOL_LOCAL, adds noexcept on move/swap, rewrites MurmurHash block-reading to handle unaligned input safely with may-alias struct wrappers, and cleans up a few incidental bugs.

Changes:

• Refactor algorithm sources (sha, base64, crc, xxtea, murmur_hash, crypto_*, compression) for consistent style, modern casts, anonymous namespaces, and .data() accessors instead of &v[0].
• Fix several latent bugs: SHA-512 free/init/start using the wrong sha384_context, missing case EN_CIMT_LIBSODIUM_XCHACHA20: in cipher encrypt/decrypt switches, MurmurHash unaligned-load safety on strict-alignment platforms.
• Add MurmurHash known-answer reference vector tests and aligned-vs-unaligned input equivalence tests; relax clang-tidy with -misc-include-cleaner and -readability-use-concise-preprocessor-directives.
