Version 1.0.0

[Summary]

StormByte System is the C++26 process and environment layer of the StormByte suite.

Spawn children with piped stdin/stdout/stderr, chain them, suspend/resume, and expand environment strings. POSIX and Windows stay behind one API.

Initial public release of StormByte-System.

Added

• Process: run external programs with piped stdin / stdout / stderr
  • Move-only ownership; starts on construction
  • Wait() for exit code (blocking, no timeout)
  • Suspend() / Resume()
  • Stream operators: write stdin, read stdout, << System::EoF to close stdin
  • Process chaining (p1 >> p2) via background forwarder
  • Stderr() to read the stderr pipe
  • Cross-platform (POSIX fork/exec and Windows CreateProcessW)
• Pipe (internal): anonymous pipes for IPC (UNIX pipe/pipe2, Windows CreatePipe)
  • Atomic chunked writes, bind/dup helpers, handle inheritance flags on Windows
• Variable: expand environment strings (Windows ExpandEnvironmentStrings; UNIX ~ → home)
• Exceptions: Exception, FileIOError, ExecutableNotFound
• Unit tests for Linux, macOS and Windows (pipelines, stdin, exit codes, move)

Fixed

• Process move no longer double-waits the same child (ownership is fully transferred)
• Failed execvp in the child uses _exit(127) instead of throwing across fork
• Removed unimplemented Pipe::BindRead(Pipe&) / BindWrite(Pipe&) declarations
• Pipes owned with std::unique_ptr instead of raw new/delete
• SIGPIPE ignored once per process (not on every Pipe construction)
• WriteAtomic treats empty input as success
• Windows command line built without a trailing space

Notes

• On UNIX, if the executable cannot be started, the child exits with status 127; the parent does not throw from the child path.
• Wait() has no timeout; it blocks until the process ends.
