 * Thai Word Break - Cluster-based segmentation
 *
 * Thai text has no spaces between words. This class provides simple
 * cluster-based segmentation for line breaking. Each Thai syllable
 * (consonant + vowels + tone marks) forms a breakable unit.
 *
 * This is a lightweight implementation suitable for embedded systems
 * with limited memory. It breaks at grapheme cluster boundaries rather
 * than true word boundaries, which provides reasonable line breaking
 * without requiring a large dictionary.
