vasilito facf0c92e0 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.

/* Ruby format strings are described in
https://ruby-doc.org/core-2.7.1/Kernel.html#method-i-sprintf
and are implemented in ruby-2.7.1/sprintf.c .
A format string consists of literal text and directives.
A directive
- starts with '%',
- is optionally followed by a sequence of the following:
- any of the characters ' ', '#', '+', '-', '0', each of which acts as a
flag,
- a digit sequence starting with a non-zero digit, followed by '$', at
most once per directive, indicating a positional argument to consume,
- '<' KEY '>', at most once per directive, indicating a hash table element
to consume,
- a digit sequence starting with a non-zero digit, specifying a width,
- '*', indicating a width, taken from the argument list,
- '*' and a digit sequence, followed by '$', indicating a width, taken
from a positional argument,
- '.' and a digit sequence, indicating a precision,
- '.' '*', indicating a precision, taken from the argument list,
- '.' '*' and a digit sequence, followed by '$', indicating a precision,
taken from a positional argument.
This sequence is in any order, except that
- flags must occur before width and precision,
- width must occur before precision.
- is finished by a specifier
- 's', that takes an object to print without double-quote delimiters,
- 'p', that takes an object to print with double-quote delimiters (in case
of a string),
- '{' KEY '}', indicating a hash table element to consume and to print
like with 's',
- 'c', that takes a character,
- 'd', 'i', 'u', 'o', 'x', 'X', 'b', 'B', that take an integer,
- 'f', 'g', 'G', 'e', 'E', 'a', 'A', that take a floating-point number.
Additionally there are the directives '%%' '%<newline>', which take no
argument.
Numbered, unnumbered, and named argument specifications cannot be used in
the same string; either all arguments are numbered, or all arguments are
unnumbered, or all arguments are named.
