//! Phase 9.2.C: Primary Word Boundary Detection Mode Implementation Tests
//!
//! Tests for the primary detection mode implementation that replaces
//! the stub process_tj_array_primary() method with actual functionality.
//!
//! This test suite verifies:
//! 1. BoundaryContext creation from graphics state
//! 2. Character partitioning at boundary positions
//! 3. Cluster to TextSpan conversion
//! 4. primary_detected flag is set correctly
//! 5. Backward compatibility with tiebreaker mode
