v0.11.0

Added

• std.Io interface is now essentially complete. All major operations are implemented:
  • Spawn and wait on child processes, with non-blocking pipe I/O on POSIX.
  • Iterate over directory entries.
  • Create nested directory paths.
  • Create files atomically (write to temp file, then rename into place), with optional make_path
    and replace support.
  • Rename files without overwriting existing destinations.
  • Batch multiple file I/O operations for linear execution (concurrent execution is deferred).
• Stream.Reader.fromStd and Stream.Writer.fromStd convert std.Io.net.Stream to zio's buffered
  reader/writer, enabling seamless interop between zio and std networking in the same program.

Changed

• net.Stream.Reader and net.Stream.Writer are now lighter, storing only the socket handle instead of
  the full stream.

Fixed

• Fixed a critical bug on Linux with the epoll backend where non-blocking network reads and writes could
  silently succeed with garbage data instead of returning error.WouldBlock.
