[Unreleased]

Changed

• Full architectural refactor (8 phases):
  • Layered directory structure: src/ + include/nxst/ mirroring domain / infra / service / ui
  • CMake build system replacing Makefile
  • nxst::TransferService — all network state and threads moved out of UI layer
  • nxst::Result<T> tagged-union type replacing std::tuple<bool, Result, std::string>
  • RAII handles: FsFileSystemHandle, FileHandle
  • Logger rewritten with nxst::log namespace and compile-time format checking
  • snake_case filenames and identifiers throughout

Fixed

• mkdir(path, 777) was decimal (octal 01411) — corrected to 0777
• Logger format args were silently dropped (double-substitution bug)
• new u8[] / malloc in IO paths replaced with std::vector
