fix(compat): use glob pattern instead of regex for code fence

Replace regex matching with glob pattern matching for code fence
detection to avoid backtick escaping issues in Bash 3.0.

Changed from: [[ "$line" =~ ^\`\`\` ]]
To: [[ "$line" == '```'* ]]

This is more reliable across all Bash versions.
