v1.8.1

Fixed

• OSC 8 hyperlinks leaked literal escape text — the ST terminator (\033\\) written inside double quotes collapsed its backslashes at assignment time, so echo -e paired the orphan backslash with the next color code's backslash and rendered visible 033[0;33m garbage after the branch/PR link. All OSC 8 sequences now use the BEL terminator (\007), which avoids the backslash ambiguity entirely and is equally supported by terminals
• Regression test: visible output (real ESC bytes stripped) must never contain literal 033[ text; OSC 8 must be BEL-framed
