Subject: [PATCH] build: normalize line endings to LF across all platforms

Add explicit file-type rules to .gitattributes so text files are stored
and checked out with LF line endings regardless of platform. This
prevents issues where Windows git (or CI actions/checkout) converts
LF to CRLF, breaking comptime parsers that split embedded files by
'\n' and end up with trailing '\r' in parsed tokens.

Key changes:
- Source code (*.zig, *.c, *.h, etc.): always LF
- Config/build files (*.zon, *.nix, *.md, etc.): always LF
- Text data files (*.txt): always LF (for embedded file parsing)
- Windows resource files (*.rc, *.manifest): preserve as-is
  (native Windows tooling expects CRLF)
- Binary files: explicitly marked as binary

Removed the legacy rgb.txt -text rule since *.txt now handles it
uniformly with code-level CRLF handling as defense-in-depth.
