Fix: Complete removal of Windows-specific CLI flag and update tests

This commit addresses an incomplete fix related to a Windows-specific CLI flag:

1.  The commented-out Windows-specific flag (`-w`) in `src/raw-therapee-wrap.ts` within the `buildCliArguments` function has been completely removed.
2.  The corresponding test in `src/__tests__/raw-therapee-wrap-windows.test.ts` has been updated. Instead of only checking for the absence of the `-w` flag, it now asserts the entire expected argument array passed to the `spawn` call, ensuring no regressions and more precise testing.

The tests in `src/__tests__/raw-therapee-wrap.test.ts` were reviewed, and no changes were necessary as the assertions remain correct.
