Disable wordexp on Windows where it is unavailable

The wordexp() function is a POSIX extension not available on Windows.
This patch conditionally compiles wordexp usage only on non-Windows platforms.

On Windows, the path is used as-is without shell expansion, since Windows
does not support tilde expansion in the same way as POSIX systems.

Changes:
- Wrap #include <wordexp.h> with #ifndef _WIN32
- Add platform-specific constructor implementations
- Windows version simply stores the path without expansion
