build: try to suppress an annoying false warning from gcc

TODO

@@ -13,7 +13,6 @@ TODO:
 * work stealing job system (see #100) + mt scheduler based on const awareness for types
 * combine version-mask-vs-version-bits tricks with reserved bits to allow things like enabling/disabling
 * auto type info data from types if present
-* suppress -Wself-move on CI with g++13
 * built-in no-pagination storage - no_pagination page size as limits::max
 * any cdynamic to support const ownership construction
 * meta non-const allow_cast overloads: (const int &) to (int &) is not allowed, but (const int &) to (double &) is allowed (support only for convertibles)
