Fix line ending inconsistencies across platforms

[gemmaro]

Problem

Ruby/C/C++ source files were showing spurious changes on Linux due to inconsistent line ending handling.

Solution

• Updated .gitattributes to enforce eol=crlf for *.rb, *.c, and *.h files
• Normalized existing files with git add --renormalize .

Impact

• Windows devs: No changes needed
• Linux devs: No more unwanted file modifications
• Large diff: Line ending normalization only - no actual code changes

Action Required

After merging, run git reset --hard HEAD to refresh your working directory.

I'm fine with this, but do Linux line endings instead (so lf).

[gemmaro]

Updated! Just modified commits that converts line endings to LF. Thanks for the suggestion.
