fix: prevent early args.deinit

[lesleyrs]

Fixes segfault on windows when using --parse-file:

std/process.zig

    /// Call this to free the iterator's internal buffer if the iterator
    /// was created with `initWithAllocator` function.
    pub fn deinit(self: *ArgIterator) void {
        // Unless we're targeting WASI or Windows, this is a no-op.
        if (native_os == .wasi and !builtin.link_libc) {
            self.inner.deinit();
        }

        if (native_os == .windows) {
            self.inner.deinit();
        }
    }
