 * Enforce spaces inside test bracket expressions [ ] and [[ ]].
 * Missing spaces cause syntax errors or incorrect behavior.
 *
 * The rule ignores `[` and `]` that appear inside strings (`'...'`, `"..."`,
 * `$'...'`), parameter expansions (`${arr[@]}`, `${arr[0]}`), command
 * substitutions (`$(...)`) and comments, so valid bash such as
 * `${CERTS[@]}` or ANSI-C escapes like `$'\033[0;31m'` are not flagged.
