build: accumulated fixes — relibc cbindgen, GCC headers, KF6 recipes

Major fixes applied:
- relibc: stddef.h → cbindgen (upstream 3be84f4b), bits_wchar-t/size-t/null
- relibc: wchar.h upstream include ordering, stdbool.h POSIX fix
- GCC: cstdlib restored, basic_string.h stold() removed (strtold workaround)
- redox-toolchain: -include stdlib.h, PCH disabled, _GLIBCXX_USE_C99_STDLIB undef
- qtdeclarative: P1-skip-tools-crosscompile.patch regenerated (hunk context)
- kf6-ki18n: P1-strtold-include.patch, CXXFLAGS, ECM version relax, qdoc sed
- ninja-build: redox.patch added to patches list
- base: DmiError::Map type fix attempts (EINVAL fallback)
- docs: gitlab→gitea URL fix, AGENTS.md updated

Remaining blocker: base-initfs DmiError::Map type drift (pre-existing issue)
