Subject: [PATCH 1/2] fix(bash): highlight command line options (--option)

Add highlighting for long options (--option) in bash to address issue #4288.
Previously, command line options like --project, --env were not highlighted
consistently across lines.

This change adds an OPTION pattern that highlights long options when they
appear after whitespace, making them visually distinct in CLI examples.
