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.

TODO list for libpng
--------------------
* Fix all defects (duh!)
* cHRM transformation.
* Palette creation.
* "grayscale->palette" transformation and "palette->grayscale" detection.
* Improved dithering.
* Multi-lingual error and warning message support.
* Complete sRGB transformation. (Currently it simply uses gamma=0.45455.)
* Man pages for function calls.
* Better documentation.
* Better filter selection
(e.g., counting huffman bits/precompression; filter inertia; filter costs).
* Histogram creation.
* Text conversion between different code pages (e.g., Latin-1 to Mac).
* Avoid building gamma tables whenever possible.
* Greater precision in changing to linear gamma for compositing against
background, and in doing rgb-to-gray transformations.
* Investigate pre-incremented loop counters and other loop constructions.
* Interpolated method of handling interlacing.
* More validations for libpng transformations.
