vasilito ff4ff35918 feat: track all source trees in git — full fork offline-first model
Red Bear OS is a full fork. All sources must be available from git clone
with zero network access. Removed gitignore rules that excluded fetched
source trees under recipes/*/source/, local/recipes/kde/*/source/,
local/recipes/qt/*/source/, and vendor source trees.

Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded.

127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt
frameworks, mesa, wayland, DRM drivers, and every other recipe source.

significant loss of precision that arises from direct evaluation when x is
small. Use the substitute from _math.h on all platforms: it includes
workarounds for buggy handling of zeros.

To save fiddling with configure tests and platform checks, we handle the
special case of zero input directly on all platforms.
