Bug: Case-sensitive process name comparison in process_t::open

The process_t::open(std::string_view name, std::uint32_t access) method uses case-sensitive string comparison when searching for processes by name. On Windows, process names should be compared case-insensitively.

Sample code:

#include <iostream>
#include <windows.h>
#include "wincpp/process.hpp"

int main() {
    const std::uint32_t queryAccess = PROCESS_QUERY_LIMITED_INFORMATION;

    try {
        std::cout << "Attempting to open 'explorer.exe' with correct case...\n";
        auto procCorrect = wincpp::process_t::open("explorer.exe", queryAccess);
        if (procCorrect) {
            std::cout << "Success: Process opened with correct case.\n";
        } else {
            std::cout << "Fail: Process not found with correct case.\n";
        }
    } catch (const std::exception &ex) {
        std::cout << "Exception encountered with correct case: " << ex.what() << "\n";
    }

    try {
        std::cout << "Attempting to open 'EXPLORER.EXE' with mismatched case...\n";
        auto procIncorrect = wincpp::process_t::open("EXPLORER.EXE", queryAccess);
        if (procIncorrect) {
            std::cout << "Unexpected success: Process opened with mismatched case.\n";
        } else {
            std::cout << "Expected: Process not found with mismatched case due to case-sensitive bug.\n";
        }
    } catch (const std::exception &ex) {
        std::cout << "Exception encountered with mismatched case: " << ex.what() << "\n";
    }

    return 0;
}

Output:

Attempting to open 'explorer.exe' with correct case...
Success: Process opened with correct case.
Attempting to open 'EXPLORER.EXE' with mismatched case...
Expected: Process not found with mismatched case due to case-sensitive bug
