Pull Request Overview

This pull request updates the random number generation across several modules by replacing the custom mtrandom library with the standard C++ std::mt19937 and associated distributions.

• Update header includes to in multiple files.
• Replace custom RNG functions with std::uniform_int_distribution, std::uniform_real_distribution, and std::shuffle.
• Update seeding logic for RNG objects using std::random_device and seed sequences.

gframe/duelclient.cpp:2264

• [nitpick] Consider explicitly initializing 'real_dist' with a defined range (e.g. [0, 1)) to clarify its intended behavior for position calculation.

(*cit)->dPos = irr::core::vector3df(real_dist(rnd) * 0.4f - 0.2f, 0, 0);

gframe/deck_con.cpp:91

• [nitpick] Since the RNG seeding strategy has been updated elsewhere, consider removing any commented-out legacy seeding code to improve maintainability.

rnd.reset((uint_fast32_t)std::time(nullptr));

Can we merge this one first?
The shuffle in duel is put in another PR.

[purerosefallen]

Will consider when test builds done

[mercury233]

Will check this later next week
