Fix formatting: break long lines for rustfmt compliance

Rustfmt requires long chained method calls to be broken across
multiple lines when they exceed line length limits.

Changes:
- Break visual_width() iterator chains in renderer.rs
- Break visual_width() iterator chains in terminal.rs
- Fix comment alignment in ansi.rs
