Fixes #29.
The
TaskManager::operator()used as the comparator forstd::set<Task*,TaskManager> timed_emitswas notconst-qualified. GCC 16 / recent libstdc++ statically asserts that a container's comparator is invocable through aconstreference, so the build fails with "comparison object must be invocable with arguments of key_type".Adding
consttooperator()satisfies the requirement and does not change behaviour (the operator only readsts_emit).
