Strip remaining Windows-only conditionals across src/src/

Removes every #ifdef _WIN32 / #ifndef _WIN32 / Q_OS_WIN block from the
organizer source tree. The Linux build is the only target this fork
produces, so the dead Windows branches were just noise. Stubs for
Win32-shaped APIs that the upstream code references (FILETIME, HANDLE,
DWORD, etc.) live in shared/windows_compat.h so the surrounding source
keeps compiling without rewriting every signature.

Also:
- Reimplemented env::DirectoryWalker / env::forEachEntry / env::Module
  / env::Process / env::WindowsInfo as Linux-only (uname, /etc/os-release,
  /proc, std::filesystem) since the Win32 branches that previously held
  those implementations are gone.
- Reduced spawn.cpp / processrunner.cpp / env.cpp to their Linux paths;
  dropped the helper:: namespace, Win-only waitForAllUSVFSProcesses-
  WithLock(), Steam Win-registry probe, and Windows mini-dump path.
- Linux launcher uses BUILD_JOBS (default 4) so docker rebuilds during
  the audit don't pin the host.

Build verified after every batch with ./build.sh tarball.
