Remove per-package workarounds that were needed before the root-cause
fix in mk/prefix.mk (which adds #include <stdlib.h> to GCC's <cstdlib>
header at prefix build time). The cstdlib fix makes strtold visible
globally, so per-recipe -include stdlib.h and P1-*.patch are redundant.
Reverted:
- redox-toolchain.cmake: removed -include stdlib.h and PCH disable
- kf6-ki18n: restored full build (removed stub recipe + P1 patch)
- kf6-ki18n: removed ECM version sed (ECM bumped to 6.11.0 already)
- redbear-greeter: removed #include <stdlib.h> workarounds in source
- local/patches/kf6-ki18n/: removed unused P1 patch directory
- WAYLAND-IMPLEMENTATION-PLAN.md v2.0: document architecture decision
that Wayland is the only supported display path. Remove all
framebuffer fallback workarounds (offscreen QPA, redox QPA shim).
- qwaylanddisplay.cpp: add fprintf instrumentation for crash diagnosis;
skip xkb_context_new on Redox to eliminate potential xkb crash vector.
- greeter-ui/main.cpp: remove QT_QPA_PLATFORM=redox workaround.
The greeter must use Wayland. Accept the crash until Qt6 is fixed.
- Ruled out: relibc calloc (zeroes correctly), libwayland proxy_create
(correct), compositor protocol (compliant). Root cause is in Qt6
generated Wayland wrappers passing NULL to wl_proxy_add_listener.
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
