Subject: [PATCH] Update Asio to 1.36.0 and refactor io_context usage

Bump Asio dependency from 1.29.0 to 1.36.0 in CMake configuration. Refactor usage of io_context::work to asio::executor_work_guard and replace io().post with asio::post for improved compatibility with newer Asio versions. Update .gitignore to exclude .cache/ directory.
