Fix ASCII header tests for shimmer character-by-character coloring

Fixed tests that checked for contiguous strings in shimmer output.
Shimmer applies ANSI color codes to each individual character, breaking
up patterns like '|   __|___' and 'dev'. Added stripAnsi() helper and
updated shimmer tests to strip ANSI codes before assertions.

All 29 ASCII header tests now pass.
