What: Internal refactoring of color definitions from hex values to ANSI color names.
Changes:
Light theme colors now use "ansi:colorName" format (e.g., "ansi:magenta", "ansi:blueBright")
Dark theme colors similarly use ANSI names
Added new clawd_body color property
Evidence: Color objects QlQ and ZlQ around line 356107-356221 in v1.0.127 (replaced rlQ and olQ at line 356102-356158 in v1.0.126)
Why it matters: While mostly internal, this improves cross-platform color rendering and maintainability. Users may notice slightly improved color consistency across different terminal emulators.
