fix(avatar): correct mirroring by generating 8 pixels per row (#6)

Fixes #6 – Ensures proper mirroring by generating exactly 8 pixels per row before mirroring instead of 9. This prevents an unintended bitwise OR condition in the center column, which previously caused extra foreground pixels to appear. The fix restores correct symmetry in avatar rendering.
