fix: strip remaining escape sequences from bash output

Browse source 
stripAnsi misses some escape sequences like standalone ESC \ (String
Terminator) which caused rendering issues when displaying captured TUI
output. Now also removes any remaining ESC+char sequences and control
characters after stripAnsi processing.
